DONT UPDATE THE JUNE/JULY 2026

Don’t update the June/july 2026 update they don’t care about how laggy the app is now that the G6 is retired

The app disappeared from my Apple Watch

The app on my Watch disappeared, and I have no reason why. Still works on my phone, but I rely on it to work on my watch as well.

G6 ending?

-Update-
Based on the automated response below, I think it’s safe to assume that this update will do nothing except remind you every 20 minutes that the G6 is being phased out, therefore it’s best not to do this update unless you want to be annoyed. Continue to use your remaining G6 patches in peace.

— If the only purpose in this update is to let us know that the G6 is being phased out please tell us that! It’s not worth updating if that’s the only difference

I love Dexcom but..

The graph has disappeared since yesterday’s update.

Discontinued but served me well through its lifespan

Sad that these got discontinued, it was a huge breakthrough in diabetes management technology and had a good experience from 2018 to 2026.
