Improving UX when user edits while a sync is occuring - Database lock

[alexbarker234]

I have an app with a periodic background sync which users often use in poor connectivity, making sync times a bit longer.

From what I understand, when the app is syncing it has a lock on any database changes (for the operations queue at least). So if a user was to edit an item and the app tries to save it, it will wait for the sync to finish which could result in a ~10s delay/loading spinner.

My question is, what is the best practice here for managing this to improve the UX?

I have attached a sample recording of a basic todo app with an artificial delay on the server side to showcase this
