I have a S21 Ultra on Sprint. It says sprint & t mobile will have access to the beta. I see other people have the beta program in their banners but I don't have that banner showing up. Any other way I can get in the beta?
My trick in the last 2012 years since I have been doing this is to turn off my phone for 5 minutes, reboot and do software update. It has never failed me. Try it.
