iOS 15.6.1 wont sync with iTunes 12.8.2.3
So I did the update to the iOS for my devices the other week as it was highly recommended with the security risk.
I was on my desktop and thought I should do a back up and low and behold neither device is recognised by my iTunes now which is 12.8.2.3 (there is no other update for iTunes on my computer available I checked). I have restarted both the devices and my computer I have unplugged re plugged tried all the options and nothing. It also doesn't with with iPhoto either.
Is there a fix for this as I can't update my computer more as there are no updates in the app store on it to update with!?
