It's a SimConnect bug or, more precisely, an undocumented change in the name of the key events, we reported it to Asobo asking for clarifications.
The problem is, there isn't an easy way to to detect if we are running in SU10 or SU11, so it's not easy to release a fix right now, because the changes to the key codes to support SU11 we already found to be working, are not working in SU10.
