Something wrong with deconz and aqara sensor

I tried to upgrade to conbee 3 over 0.5 years ago, I spent a whole day getting it to work and found out that it wasn’t fully baked yet. Now I’ve tried again with the latest firmware on conbee3, and have experienced exactly the same thing. I’m running home assistant and deconz via addon 7.00(2.28.1) fail with lumi.sensor_magnet.aq2 aqara door windows sensor, which does not update or loses connection. (Maybe other devices too?)

conbee 2 with ha addon 6.23(2.25.3) work perfect
problems with conbee3 on ha addon 6.23(2.25.3)
problems with conbee2 and conbee3 on software 7.00(2.28.1)

I can see that several others have the same problems, will this be solved? Or do I have to find another zigbbe cordinator to be up to date? I have many devices and would be completely satisfied with conbee3, as you can put a backup in from conbee2 to conbee3 without having to re-pair and name all zigbee devices.

It seems to be a software problem in 2.28.1 (ha addon 7.0.0)

Is the solution perhaps the new T1 door window sensor from aqara?

Feeling very frustrated :-/
