FYI under this latest release it seems I can no longer block a community, nor subscribe to one. Clicking the block button used to change it to say “unblock”, it doesn’t do that anymore. Similar issue with “subscribe” no longer changing to “unsubscribe”.
Edit:
Turns out that, even though I have been able to switch between two logins since updating to this version, it wasn’t actually logging in. Manually removing the account from Thunder and then re-adding resolved the issue.
