Probably a bit of a case of mixed community messaging. People say "Go play something else" because usually that is an option for Playstation and PC players (either via tabbing out for PC players or picking up something else like a laptop or switch for playstation players). Obviously in your case that wouldn't apply, but people dont have a good grasp of everyone's individual circumstances and sort of just respond as if someone were in their own circumstances.

As to whether the launch was a failure or not- I think it was messy and I think Square do as well given the response. I dont have any advice on refunds since I know nothing about the refund policies of square but I hope either the queues get quicker for you or you get your money back
