When someone opens the database from their iPad and go to type their employee ID, the first number will show and then disappear. I've included a video showing me opening the database and going to type "92". You will see the 9 get pressed and show up for a split second and then disappear.
My startup script opens the page you see and goes to the "User ID" field. This is the only field that is affected like that, so I'm not sure if it's because that's the first keystroke while having the file open.
This happens on all four iPads when opening that page. Even if I open the page and wait for 10 seconds then type 92 the 9 will disappear like in the video below:
