I had to change a few things to a PowerApps custom SharePoint form. After publishing, I could not save new items in the list anymore. After trying out all kind of things, I decided to abandon my changes and revert back to the version I know was working. By restoring the app, it also went back to PowerApps release 2.0.762. Now my form was working once again.
As I became increasingly suspicious about the nature of this problem, I decided to change just the display name of one of the fields (can't save without a change) and publish once more (to release 2.0.783). Guess what, I couldn't save new items in the list anymore.
Just great, wasting half a day trying to find out what I've done wrong only to figure out this is yet another backend change breaking things. Don't bother looking for release notes, there are none.
This "InfoPath replacement" really feels unfinished.
