OK, I see what you are saying now. I have a similar thing happening in my app when I tap on the calendar. However, it only happens on the published app in my chrome desktop browser. It doesn’t jump around for me in the glide editor or in chrome on my android phone. Your app on the other hand appears to be doing it in the editor, desktop and phone browsers.
I’m guessing there is an issue with other actions getting fired when they shouldn’t be. I noticed this a week or so ago with another app I was playing with, where adding a row in one part of my app was causing the set column action to fire when the row showed up in a list. I wonder if it’s something similar where some of your other actions are all firing, which causes the screen to jump.
This is an example app where I’m experiencing the action getting fired when it shouldn’t.
