I’ve had this happen to me in the past and it was due to a visibility condition not being met. Mine was based on “is signed-in user.” Do you have any conditions assigned to the text entry component?
The app ‘brings up’ an empty keyboard. It’s like there are no keys n the space where the keyboard should be. There is the ‘up’ and ‘down’ chevrons on the left and the “Done” on the right. Just no keys.
I reverified that it works in the dev environment running MacOS. I have demo it before without issue.
I rebooted my phone and the empty keyboard screen works correctly.
I tested the keyboard on multiple apps and only Glide showed the “empty” keyboard. Just before this happened I got the Glide “white screen of death” and closed the app and rebooted it. At this point the keyboard did not properly within Glide but did work with all other iPhone apps.
