@Mel dCP I know I downloaded the Spike ap so I could reset my transmitter , but I know I was warned that the Spike ap and the G6 app both probably wouldn't work at the same time. In my case the G6 kept going and Spike stopped. I ended up deleting Spike anyway as I really just wanted it for the moment.
But I am wondering if you might be running into the same thing where both running aren't compatible now? Just a possible guess as I have no clue!
Plus, my newest iphone update shut down Dexcom Clarity reports for about 4-5 days. The CGM part still worked fine. It turns out the new security measure on the iphone update blocked Clarity from working right. They have now fixed it but suggested it could happen again and not to automatically update my iphone until I know it's "safe".
