On a whim two days ago I turned on the toggle to download the developer beta on my software update page on my 15 Pro Max. It downloaded 18.1 but I think that is not the newest version because RCS support isn’t there and neither is the Apple Intelligence. However, the newer version isn’t being offered for download and I’m afraid I did something wrong. Any help would most appreciated. I think the only reason the option was there to download the beta was because I did it four or five years ago on a previous iPhone.
