If you contact support you can change devices as many times as you want, especially if you’re on a beta trail. The device limit is only there to stop account sharing.
There is an app for the series x/s coming next week. So will be interesting if this is a simple port of the current one or will have some new features added.
This is beyond a joke. I’m not on the beta and have been eagerly anticipating this app update for over 2 years now. The ‘beta’ app is clearly working so why not just release that? Even if it’s buggy literally anything would be better than current app...
