ISSUE: Sync no longer working?

I tried reinstalling this RemNote plug-in, re-inserting the access token, etc.
Readwise doesn't see the connection to RemNote.

I have about 70 books synced but there are around 1000 books I'm hoping to sync (so starting over from scratch is fine)

Is this plug-in not working, for now, or is there a way to start over to get it working?

Thanks so much for making this!
