Two Weeks ago i had the same problem. Did a recovery and everything worked fine (recovery set firmware to RC46 than i could update to rc47)
Yesterday i had a other problem. All my zigbee devies didn’t respond any more. Zigbee was started and in the developer app all devices ware present with a route, but no respons.
Had to do a recovery again. Now it works fine.
So there are big zigbee isues after firmware RC 43
