I have had an issue with advanced quests requiring "Fight with a Team from a Single Faction" in both Classic Arena and Tag Team Arena not completing upon quest fulfillment.  

I am playing in most current version of Plarium Play desktop app on Windows 10.

Currently it is not recognizing completion in Tag Team Arena, and I have noticed the same issue on several other days.  I have also noticed the problem when the quest requirement is "Play with a single faction in Classic Arena" as well.  This issue has caused me to miss out on a number of days of rewards from fully completing Advanced Quests for the day. 

I have even tried making all each of the the 3 tag teams of a single faction each, but quest will still not complete.  As you can see from screenshot.
