Fw update kills po16

hi guys, the newest fw update seems to have major issues with my po16 controller. it flashes green and connects and disconnects all the time. FW 2025-05-19 1122 seems fine for now
cheers

To my knowledge there weren’t many changes in 1.3.6 that could cause such behavior. Is this a Series 2 Grid module?

yes it is a series 2 grid module.
