I don't know or care about any of this technical stuff, all I know is I was playing just fine with all my content this afternoon, and now all my purchases are gone. I have a linked account I use between Android and Switch, but this issue is effecting my Android at the moment (it's too late for me to try the Switch, but it was was working this afternoon too). I've signed out and back in, I've checked the store to see if they just needed to be redownloaded, but they show up as available for purchase
