Do you have any addons or extensions that block cookies from the sync dns?

Thank you.

I have the same issue. Sync stopped working with the last update. I have tried disabling addons and extensions. Makes no difference.

I get a message . "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action."

When I try to go to the Sync page I get:
