Switching carriers on an unlocked S24u can sometimes cause issues with beta program access due to carrier-specific settings or incompatibilities. Make sure your new carrier supports beta participation for your device and try re-enrolling in the program through Samsung Members. Clearing the app cache might help too.
By the way, much like troubleshooting phone issues, finding the best players can require patience and strategy hope you get back into the beta soon!
You have to notify the Beta administrator that your carrier has changed. The new carrier may not participate in the Beta and now you are ineligible to participate. As I understand it, the Beta is limited to T-Mobile users.
A lesson to be learned. Do not switch carriers if you are in the middle of a Beta test.
I don't know, as I am not part of the beta. I would assume you would have gotten instructions when you were accepted. I know that somewhere in this app is a beta forum. You could try direct messaging one of the moderators by clicking thir ID on any of their posts.
