iPhone 8 Plus TestFlight iOS Beta Install Failed

Hi, I just got my new iPhone 8+, tried to re-install the TestFlight latest iOS Beta, and it keeps saying cannot install. Does anyone know what the problem is? The regular Channels iOS App installed just fine. It’s just the Beta that is not installing.

The actual error message is “Unable to Download Item”

I pushed a new build to TestFlight- maybe it will work?

Yes. Thank you.
