Categories and Folders collapsed state don't save or sync

On Android, the collapsed categories and open folders don't seem to save correctly. I'll open a folder, close the folder, do some other things then close the app. The next time I get back, the folder is open again, which shouldn't be. This is the same with categories. They do not seem to save the states even though I've spent enough time for that to happen. Also, the states of categories and folders on desktop do not sync onto mobile, which, in my opinion, should be a feature. If it were, all I'd need to do would be to collapse the categories and open the folders on desktop, then have all of that synced on mobile.
