I have used this firmware for 4 weeks and had issues with poor Wifi as the devices would lose connection, I have four devices all in the same location and every week one of them would drop the connection and the only way to get them back was to power cycle them off then on.
I have reverted back to the stable firmware (20211109-131033/v1.11.7-g682a0bd) for now as having them drop connection is a bit of a pain.
