How do you unblock? I don't see any settings in Sync for unblocking a community you block in this way. Is it only accessible through the account settings by logging into your home instance with browser?
Also, is there an easier way to add to the community filter list in Sync?
OP specifically said block, not filter. Blocks are recorded on the server and work on the website, too, or other apps. Filters only work on Sync for Lemmy.
