AIO EPS lag after recent update

My AIO used to have instant (0s) switchover when the grid was lost but now it takes closer to 60seconds.

This is after updating to D0.612-A0.612 and BMS10. Is this a known issue?

Support told me the N-PE toggle was incorrect and changed it. Now the 0s switchover works as before but restoring power causes the AIO to trip offline and I lose power.

Any help appreciated!
