Whenever I try to access Dual Track after doing basically anything else in game beforehand (not even a lot of fights, just a single fight), my game CRASHES and closes.Started JUST THIS (I mean LAST) month, March update.I have to go to Dual Track as the first thing I do when opening game, or else Dual Track crashes.So maybe your device is a little better, but still whatever the new problem is causes display problems for you as well.
Thought you were referring to sort of GRID PIXELLATED ISSUE in upper purple color region of screen ???Is that not it ?Do you mean why GOLD Track is Locked on those days ?If so, that is how just GOLD works.Even though you have moved past that day in Platinum, or have done weekly Booster Solo Event, you still need to wait for that day to come before claiming the Gold item.Not a bug (if that's what you mean)
