Issue with Aqara Opple Remotes after upgrade

I upgraded from core-2021.6.0 to core-2021.9.0 (now on 9.3) and since upgrading my opple remotes have stopped sending zha_event events. I am using the ZHA integration using a HUSBZB-1 and until the upgrade worked flawlessly with my 20 other zigbee devices. I tried reverting ZHA to an older version and did not make a difference. I removed and readded the remotes (I have the 4 and 6 buttons paired) and then it works great for about a day before disconnecting again. The battery shows as unavailable in devices until I re-pair. Any ideas?
