I got a like on a reply after today's update and it was sent to the "miscellaneous" channel instead of "likes". Also, there are two "miscellaneous" channels now.

lol should probably give that a different name then. the second Misc category is added by the system automatically

I'm making a github issue for the notifications channels because activity notifications also go to the system miscellaneous channel, so I think none of the new notif channels are doing anything rn lol
