So not compatible with UP2.01?

:?: :?: :?:

What makes you think that it shouldn't be compatible with UP2.01?
DeviceLink is deactivated in online sessions. Full stop.
Everything else, be it stock 4.0 IL-2 or any modded version, regardless whether it's a mod pack like UP2.01, HSFX , who-knows-what-else-pack 0.8963636 or any highly modded personal installation: No problem, it works.
