Missions still not working correctly

Missions are not displayed (or counted?) as completed, though their goals were fulfilled. Valid for FWotD as well as the "New season"-Missions Part 2. Yesterday it worked for one moment, but then again it failed to count my game. I know several other players that encounter this, too.

I already filed a ticket via the in-built client feature, but I am not sure if / how I will get feedback, so I post it here as well.

A little sad since I will probably miss out the 900 BE reward. :(
