Dexcom G6 cannot connect with iPhone 11 (iOS 13.1, 13.2 & 13.3) & Apple Watch Series 5

Have tried various pairing, disconnect, reconnect, restart, uninstall of the app with the watch 5 and without the watch, none of the options work. iPhone 11 bluetooth is not connecting to Dexcom sensor. Is this a flaw with Dexcom or the new iPhone?

I really hope that someone can get this resolved asap. Very frustrating to see every iOS upgrade has become a life-threatening decision to make for a Dexcom user.
