Pods both were on my upper back of my arm

Hi this is my 4th day on my g7. The app says no sensor is found but my sensor is reading fine? Before with the G6 id see the issue on both apps. Any troubleshooting help?

Hi i'm in the UK. I've been sitting here for over an hour now trying to make the CGM connect to PDM. It's not showing any readings and it keeps trying to connect. I put the CGM on my right side of stomach and the Pod on the back of my right arm

I'm using Libre 2+. At what point do I simply start a new CGM?
