23.20 issues on brand new FR955 Solar

I’ve just purchased a brand new Forerunner 955 Solar as a 2nd watch but since updating the software I have a few issues. Connect IQ store won’t allow me to download an app in this case the hydration app, it allows me to hit install but then just stops about 5s later and never makes it to the watch. 2nd issue device back up completes its back up but then doesn’t show up in the back ups? On my Epix pro it shows up all my previous back ups including a previous Forerunner I had? 

Anybody else having the same issue?
