I had this problem recently and it is very frustrating. PDF won’t display. I tried to open it on my Mac, iPad and iPhone. Still, I received the same message. I tried to download the PDF document on my Mac and open it with Preview, still no luck. However I was able to view the PDF document. You may experience this problem too. Did you try to open a PDF document in Safari or PDF preview in Mail? And you got this message? This short article explains what I did to resolve this problem:
Please Wait… View Your PDF Document
These type of PDF documents are called Dynamic XFA. XFA stands for XML Form Architecture. As of currently, Safari (and also Chrome and Firefox) do not support these type PDF forms thus Dynamic XFA based PDF documents cannot be opened in browsers.
You can view these type of PDFs by downloading and installing Adobe Reader on your Mac. However, you cannot view these type of PDFs, as of now, on your iOS device, the iOS Adobe Reader app currently does not support this.
macOS

Go to this URL: https://get.adobe.com/reader/
Click Download Now. And then follow the installation instructions.
After you complete the installation process, now go to the PDF document and save it on your computer.
And now open it with “Adobe Acrobat Reader DC”.

iOS (iPhone or iPad)
As stated above, currently you cannot open these type of PDFs on your iPhone. You need to open it on your computer. Downloading and installing the Adobe Acrobat Reader app on your iPad or iPhone will not help you open these PDFs. When you try, it will say “this form requires Adobe Acrobat Reader DC for Mac or Windows”. Currently only desktop version of Adobe reader supports this.

What Does Arrow Icon Mean? Location Services Explained

Do you see an arrow icon at the top of your screen? Is it sometimes blue, sometimes hollow? And are you wondering what this icon means? That means that your phone is currently accessing your location. This icon can be in different format/colors. Different colors mean different things. This article explains what these different color arrow icons mean and how you can disable, if you want to do so.

In short, when you enable Location Services, a black or white-hollow arrow icon may appear indicating that your device is using Location Services (e.g., maps, Camera, weather apps, etc). When you enable your Location Services, you are letting your iOS device determine your location. Your iPhone or iPad uses GPS, Wi-Fi, Bluetooth and mobile networks to obtain the most accurate location. When you disable this, it will be disabled for all apps.
Some apps may need this enabled as they may use this information to work correctly. For instance, you may set up location based reminders. Or Find My iPhone will not work if you disable Location Services. Without Location Services, you may not be able to use map apps. You may enable or disable this for certain apps. Note that Location Services may drain your battery.
Arrow icons
As I stated above, if you see this arrow icon, that means that your iPhone is accessing your location:

A hollow arrow means that some apps (one or more than one) are actively using geofencing. This means that this will trigger an action when you go to a set location. For instance, you may set up a location based reminder (e.g., “set a reminder to call Bobby when I am home”) and when you are home, you will be notified. Obviously your iPhone will have to use Location Services.
A solid (black) arrow means that your device is actively accessing yoru location. For instance, when you use a Map app, you will see this.

How to show or hide the arrow icon
You can hide or show the Location Services icon easily. However you can only show or hide System Services Location Services. Note that this is not enabling or disabling Location Services. If you want to turn on and off this, please see the following section.

On your iOS device, tap Settings > Privacy > Location Services
Scroll down and tap System Services
Scroll down and toggle off “Status Bar Icon”

How to turn off and on Location Services
You may want to disable this for various reasons. For instance, you may disable Location Services to extend your device’s battery life. Note that some apps may not work if you disable this. Here is how:

Tap Settings
Tap Privacy and Location Services
And toggle off “Location Services”

You want to enable Location Services but you also want some apps not to access your location? You can also turn off and on Location Services for certain apps. Here is how:

Tap Settings
Tap Privacy and Location Services
Find the app that you do not want it to access your location
And then select “Never”. This means that this app will no longer use Location Services. There are other options that you may also choose. “While Using the App” means that the app will use Location Services when it is being used.

Location Services Not Working?
You may try to reset your Location Services by going to Settings > General > Reset and tap Reset Location & Privacy.
