Great, now my post has been deleted!!!

My husband and I have been trying to share a shopping list for months, which doesn't always work. It often takes over the last status and overwrites the current status. This does not change if you share the list, i.e. log in with 2 accounts or log in with one. It also doesn't seem to matter whether you close the app or synchronize with the server before closing it. What are we doing wrong?

To be on the safe side, I have now copied this text. It may now appear several times.
