I tried upgrading some of my skins, and unlocking variants but it always says Purchase Failed. Anyone else facing this issue?

I usually face this situation where most of the teammates I play with always buy during this round. And if we lose, this results in a 11-12 where we can only half buy and the enemies will definitely full buy. If we're lucky, we can bring it...
