Unable to update to IOS 15

When I try to update wirelessly on my phone, I get a message saying it is unable to install. No information is given as to why and no error codes are shown. Apple support recommended I try updating manually using ITunes on my PC, but when I try to check for an update it says my IPhone software is up to date when it’s clearly not.

iPhone 11 Pro, iOS 14

Updating for future reference in case anyone has the same issue!

Apple recommended I back-up my phone to ICloud and then factory reset it. Then I restored it to my ICloud back-up so I didn’t lose anything, and I was able to update it with no issue!
