Having upgraded to Big Sur I found that sync is no longer working.
I reinstalled Edge (GA, Beta and Canary), signed out of my account, signed back in ... 'setting up sync' shows constantly, but edge://sync-internals/ shows 'Initializing' and Get Updates shows the message
NETWORK_CONNECTION_UNAVAILABLE
Don't know what the issue is or how to rectify. Have raise a support ticket and have heard nothing in response.
Is anyone else experiencing this problem?
While waiting for someone to look at this - does anyone know where / how I could retrieve my favourites in a local or server cache in the meantime?
