Little 1 in upper right corner of Apple I pad, how to mark as read?

Hello Joshua,

I hope you are doing well. Per the description, I understand you want to remove the notification dot from the application icon.

To do so, you can open the application and click on the bell icon on the home screen's top right, just beside your profile icon.

If there are any new notifications, reading them will remove the dot.

The other option would be to go to the settings app-> scroll down to locate Acrobat-> Notifications->, toggle off the option saying "Allow Notifications"-> Restart your device-> Toggle on the same option.

Let me know if either of them works for you.

Thanks,

Souvik.
