I'm using the OC2 headset with Win10 and 8.0 APK which is running without any problems. Updated to 9.0 APK , no changes to OC2 or Win10, started encountering intermittent problem connecting to SMB server, in my case it's an external drive, then, no connection at all, rebooting everything didn't resolve the problem, re-installed 8.0 APK and we're up and running, I don't know if anyone has encountered this problem, could be on my end, just an FYI.
