..... The staff seem to be as confused as me with one respondent suggesting the quests ran from Wed - Sun and others suggesting Thur - Sun. .....
No idea, Ken. The emails go to junk and I rarely have the time or inclination to read them. I just clicked the quests tab in the app (trophy icon) and saw offers for Thur - Mon inclusive.
Bit cheeky of the FN guy to say you're mistaken but they'll give you the money as a gesture. Your Mon screenshot clearly says "6pm-2am", "completed", & a "Yes" tick mark. It's identical to Sat and Sun and you got paid for them!
