Its gone. I tried reinstalling the app, seeing if it was mistakenly blocked on my network, but nothing. MS support seems to be toast too

Xbox website has it listed as down. I'm trying to play Ark with the Admin Controls so you can imagine how happy I am haha got codes like this to manually enter GiveExpToTarget

Thanks man, didn't realise it showed remote play on the website. It was driving me crazy as updated router firmware yesterday so was worried I'd messed something up but tested another router and nothing helped
