I'm in the beta program on my s26 and it said that im joined but I dont see the update, I've tried rejoining, restarting the device, waiting a few days, reinstalling this app
Did you join recently? It could be that they're not allowing any new downloads. Samsung indicated this week that the stable build for S26 will be available "soon."
Samsung probably closed the beta since the next release is likely going to be the final stable release of UI 9.0 which will probably be in 2 to 3 weeks perhaps with October's security update.
