Problem with 5GHz Wifi on iPhone 12 Pro

Hey!

I just got my new iPhone 12 Pro yesterday and I’ve noticed some problems with the 5GHz WiFi at home. For instance, some apps won’t download data, the Apple Music app won’t play music and the Apple Photo app won’t update/download photos over the 5GHz network. Other services work normally, I can also browse the web with Safari over the 5GHz network. Some things work, some don’t. When I switch to the 2,4GHz network, everything works as normal, no problems at all. All my other devices though, for example iPad Pro or iPhone 11 Pro don’t have any issues whatsoever with the 5GHz network. It’s just the 12 Pro.

Tried restarting both my router and iPhone. I also deleted network settings on iPhone. It didn’t help.

Does anybody have an idea what this issue could be with the 12 Pro?

iPhone 12 Pro, iOS 14

I had the same issue from purchase with the iPhone 12 Pro Max, checked IP, hub and DNS with no fix, took it back to apple and showed proof of where mine has issues connecting to the 5Ghz signal but, was working fine on 2.4Ghz unless AirPods Pro was connected and in use, then neither would work. The iPad Pro, and another iPhone XS Max were all working fine as normal.

Once I got the new iPhone everything was working fine until a backup and restore caused the issues to start again, from this I forgot the networks before backing up and restoring again, since then had been working fine,

Updated to 14.3 over the air and issues restarted, so I do have a feeling it’s software related more than hardware.
