@rene I see that you added the "Testing Bounties" room which is a room that Martin Sleziak created in order for us to test Bounty and HNQ feeds. However this room:
chat.stackexchange.com/rooms/109935/hot-network-questions- is the main one where we are following HNQ feeds. When there is some problem with that feed (for example, a question gets missed), we have been doing some testing/troubleshooting in this room.
