The problem is even if vendor make a patch quilckly, he cannot put it on his own site before it become available on the MSFS Market (and it can take time). This system is bad in term of user experience.
Personnally, i prefer to buy on dev site.
Ok, that mean less money for FS to make the sim evolved, but why I would give MS a part of developer’s money juste to have a Tom Cruise extension when so many bugs remain (and new created !).
