iPhone 6s won't accept iOS upgrade

any help on how to get my iPhone 6s to upgrade to iOS 15? I have tried many times and the download and validation of the update occurs but the install now button never shows. The phone cycles and starts downloading again.


Please advise.

Try doing it on a computer using Finder/iTunes for the job

Update your iPhone, iPad, or iPod touch with the Finder - Apple Support
