Experienced PowerApps builder having a major issue! My gallery items show blank when I publish the app. They show fine when in studio. I have tried everything. Originally this issue surfaced with the drop down control so I switched to a gallery and it does not work.
Tried to go to classic rendering and that did not help.
Data is populated from a collection. Even if I just add plain text it fails. Works fine in studio! Nothing on web app or online. HELP!
