I also have this issue in the new version of the app on Android! When I change the order of the tiles on the Home page, and close and reopen the app, all the tiles are (sometimes) back to their original location. The same applies to the tiles within a folder.
I was able to replicate it this way:
- Reorganise the tiles on the homescreen, and close the app
- Open the app again, reorganise the tiles within a folder, and close the app
- Open the app again, and now the order of the tiles on the homescreen changed
And when I change the order of the tiles again, than the order of the tiles within a folder resets. Here's a video recording I made.
