If you haven't you could try the "Re-Sync Favorite Tags filter" link...
Do you have the show details link? -- if you do not, maybe the bug is that until you have a single tag (or until it thinks you have a single tag) you cannot "expand" to re-sync.
My guess is that until it thinks you have at least 1 tag, you've not got access to the refresh link. This to me sounds like a bug. Although I presume the situation will resolve after a period of time when a sync is scheduled.
Edit 3 - Potential work around
You might be able to work around the problem by just doing what the link would have done if clicked (obviously not ideal).
- On the page where you can see your favourites (or not see them either way) look at your URL. It should be something like:
- Change the URL to be the following (obviously substituting
<NUMBER> for your number from step 1. URL:
- Hit enter (or whatever) in your browser to potentially cause the refresh
This would be the equivalent of clicking the link if it were visible/accessible.
This may not work but presumably will. Confirmed by OP that this worked.
