I have an iPhone 7 plus that I put on the beta for iOS 12. After it released to the public I went in and deleted the beta profile so I would be back on the normal track for software. The odd thing is my phone still wants to install the latest iOS 12.1 beta. I do not wantt to do this because I hope to get a new 10S soon. If I back up my phone to iCloud with the beta on it I won't be able to restore to a new phone since the phone will only have the normal iOS 12 on it. How can I get rid of the beta on my phone without losing all my data?
