hmm... I never encountered any problem with my play. although I got to run the gacha using 30 gems for a guarantee 7-star twice due to connection problem one, & got 20 units then.

The friend list (to search and receive FP), premium shop, gacha and arena are available when you are connected to the net/data only, otherwise those always get error.
