Does not connect to some ATEM devices with firmware 9.5.1?

Does not connect to some ATEM devices with firmware 9.5.1:

ATEM TV 4K8
ATEM Mini Extreme ISO (SDI)

Does oddly seem to connect to with firmware 9.5.1:

ATEM Mini Extreme ISO (HDMI)

May explain why my test environment with an ATEM Mini Extreme works, but my production environment with new gen Constellation does not connect... Will try the Mini in the production environment tomorrow but this is bad news :(

Yeah... I am planning to do some testing this week as well.
