I can't save any changes to an app

[d6410]

I've posted before but didn't get much help. Everytime I save an app it saves in edit mode, but does not save when you play the app. The changes simply don't exist there. If I want it to work I have to save it as a new app. Changing browsers doesn't work and I do not have access to contact PowerApps support since I'm not an admin. Please help!

Is this a model-driven app, or a canvas app?

Are you publishing the app?

Are you playing the app in the studio, or in the player?
