Yes they have.
They have been aware of the issue for several weeks, (month?)
There isn’t a lot of feedback from them on this, and there are so many posts from users with issues, so it’s hard to find them again!
You do have to read a lot of threads in here to find the odd bit.
Understandably they probably don’t want to announce that there is a problem with simconnect.
I actually got most of my info from Pete & John Dawson’s FSUIPC7 forum site.
They have been in touch with Asobo.
This is a link to an early post when the issue first came to light…
