@tboggs It updated on Friday after I posted and updated again today or over the weekend. It is behind x64 but better.
As for favorites sync, it appears to be turned off system wide. I do not see syncing between canary on two x64 machines or between canary and dev or beta on the same machine. I don't see any syncing. Edge mobile on both Android and iOS still have my favorites from 11/25 though I have made several changes on my PC since that time.
