I have been trying to update my phone with the 14.7 iOS update but everytime I try it says failed because I’m not connected to the internet even though I’m connected. I tried restarting my phone but it still doesn’t work.

Im having the same exact issue and everytime I unlock my phone it reminds me of the update a cannot download 14.7 super aggravating.
