As of the recent update, the extension no longer seems to be working. There are still groups but no ability to filter by group at the top of the subscription feed. Is there a limit on how many channels it can handle?

Edit (reply to developer): I tried disabling all other extensions (in LibreWolf), but it still doesn’t show the group filters at the top of my subscription feed. I get the same result in Firefox. I’m not sure what would be causing a conflict, as I haven’t recently changed anything about my browser configuration.

Edit (reply to developer): I wasn’t hiding the groups, but I did notice that the groups had disappeared. So I restored from my Chrome settings, and it seems to be working now.
