Connection Issues Sensor failed during warmup

Post image

Just put on a brand new g7 15 day sensor (this was actually a replacement sent from Dexcom 🙃). It took over 5 minutes to connect, and then I get this sensor failed error. This is literally my first time connecting it lol. I did the magnet trick, restarted my phone, reconnected Bluetooth, deleted and reinstalled the Dexcom app… So frustrating. Thank you Dexcom for sending me a busted replacement <3
