I tend to use GrayJay. But i’ve never used it for twitch. I do however see there is a beta version for twitch on the app ^^ (it’s a all in one app so it does support YouTube, oddysey, kick and basically anything you can think of)

Because they don’t allow VPNs and for some weird reason, they consider it cheating. Got banned once, but that was during a time I got in with a VPN. For some reason, my steam ID wasn’t banned. But more of me and my IP in combination. Back then, I could just switch origin IP. Now its jot really possible and quite annoying ^^;
