Zorro help with M2 Evo

Hello, looking for some advice with radio master zorro. I have one for my M2 Evo ii and it no longer reliably connects to the evo. When I power on the heli after the radio it declares that telemetry is recovered but the evo keeps beeping and the LED2 light blinks. Used to be solvable by redoing the battery connection on the evo but that does not seem to work anymore and can't find a solution that does.

Anyone have any tips?
