Reconnect to Sync

I’ve tried and tried to connect Notes to my Firefox account (so I can sync Notes between browser and Android app). No matter what I do, it keeps returning to the Reconnect to Sync button at the bottom of the Notes panel.

Is there something I’m missing about the sync feature?

Thank you so much for any help you can offer.

I have also the same problem. No matter what I try, it keeps telling me “Reconnect to Sync”.
My browser is always in private mode.
