iPad App not syncing and crashing

I’ve been using the anking deck for boards, and I cannot get my iPad to sync. I do my reviews on my laptop when I can, but i like to have the option to do them offline and then sync again when I get home. Every time I try to sync from my iPad on anki mobile, the app crashes after syncing for a few minutes and I lose my review progress.

Please force a full sync in the preferences screen, and sync again, uploading if you want to keep your local changes, downloading if you want to keep the changes from the computer. Does it succeed? Does the Check Database feature report any problems inside AnkiMobile?
