reinstalling iOS app using backup

I want to make sure I do this right. If I reset my iphone and want to reinstall the app, but retain my current study history, what are the steps?

Do I need to save a copy of the most recent backup that the app created (made this morning) to an iCloud Drive folder (like Documents), and then move it to the app's backup folder once I've reinstalled it?

Or is the only way to sync it to the mac app before resetting the iphone, and then sync to the mac app again after reinstalling the iOS app?

    There is an Export Library option you could have used, but that is currently broken. We have someone looking at that now.

    In general, if you remove an iOS app, all data is removed, except what is in the cloud. So as long as everything is synced up, it should come back from the cloud. But at this point, making a backup, and reinstating that without iCloud would be tricky.

    If you can wait a week or two, I think we will have the export working. It was broken by adding in new internal backup features recently.

    Kind regards,

    I'm confused. You say that "all data is removed, except what is in the cloud. So as long as everything is synced up, it should come back from the cloud."

    That's fine, but in the past you've said that the app doesn't store the database in the cloud:

    nor does it sync backups to the cloud:

    So how is it able to restore my data to the app if I wipe the phone and then reinstall the app?

    The data in the cloud is sync data. It has a very specific form. It is not simply a copy of your local database. Basically it is a set of rules to build your library. By playing back that sync data, it can build up your library. Like a recipe to make your database, but not the database itself.

    Kind regards,

    sorry, I replied to the old thread rather than this one.

    my reply to the above>>>
    I'm not sure that would have worked in this case. I had reset cloud sync on both iphone and macbook about a year ago and never turned them back on (and I deleted the app's library folder on the macbook). Would the iOS app have still been sending this sync data to the cloud?

    At any rate, after backing up the iphone, I decided to turn on sync on the phone, let it complete, and then turn on sync on the macbook (which took about an hour and ten minutes). I had been wanting to switch to using the macbook app in order to study notes whose scheduling was thrown off by a bug that you finally corrected a while back (where it continued to schedule notes as if graded correct after they were changed back to incorrect grades). Then I'll sync back to the reset phone later on and start using that exclusively again.

    to which I got your response that the cloud reset would have indeed made a restore from cloud data impossible.

    When the Export Library option is working, does this save the study history as well?

    The export library has everything. It is literally the database just zipped up.

    Kind regards,
