Hi,
I have a text control and a button control placed at the bottom of a screen with the displaymode property connected to a 5 second timer.

When the timer hits 5 seconds, the displaymode switches from disabled to edit. The text and button work as intended on internet browser and android phones. However, both the text and button are invisible when iOS is used to run the Power Apps app. Despite this, I can interact with the button to trigger it's onselect property (which is a simple navigate to another screen).

The issue isn't replicable on all iPads. I've tested five different iPads of different models, and this "invisible" text and "invisible but interactable" button only appeared on two of the devices.
I've tried replacing the text and button controls, but the same issue occurs. I've also tried clearing cache and updating Power Apps on all the iPads, but the same devices still don't show these text and button controls specifically (all other controls, screens, etc. work as intended in the app)
Anyone seen this behavior before? More importantly, what's the fix?
