Unable to Check for Update IOS26 Beta1

I’ve updated to iOS 26 Beta 1, and now I can’t revert to an earlier version because my iPhone automatically created a backup using the iOS 26 version. I’m also unable to check for updates—my device can’t retrieve information from the server, so it’s not detecting that Beta 2 is available. I need help resolving this issue, please.
