Hi
@ElenaP,
I used to use a G6, now using G7, always with iPhones. I don't remember ever getting a message from Dexcom re impact of iOS upgrades, but know with the more major upgrades the tech department, when I've contacted them, sometimes warn to delay before updating while they're testing/updating the Dexcom Apps. Most of the time I don't notice any issue with new iOS - with my G7 App, iOS 17.1.1 hasn't had any impact. Has your G6 settled down? Maybe go through all your alarms & threshold settings, plus switch phone off and restart and see if that helps?
