I just installed what I "thought" was OS 27.2 to my iPhone 11 - using my Mac internet connection. As I was watching the process, I was seeing the file being downloaded, and it was clearly labeled as OS 26.6.2
Upon completion, when I checked what the iPhone "About" showed, it showed as OS 27.2, though I had seen 26.6.2 had been installed.
Found that all very confusing. Not sure what was an actually installed. Anyone else have a similar experience???
