### Stacktrace

_No response_

Start in NotesServerSyncTask.java at pushLocalChanges (line 150), then follow its caller at run (line 99). Reproduce synchronization with the reported app and server versions while checking the ManuallyLockedException details. Done means newly created phone notes synchronize reliably to the server without this failure.
