Why do I see “username or password are incorrect” when I try to log into the Dexcom CLARITY app on my smartphone?

Login issues can be caused by having the incorrect country or region selected in your smartphone settings. Within smartphone settings, set the Region (iOS) and Language/Region (Android) to match your Dexcom account then, reinstall the Dexcom CLARITY app and try again. Please contact your local Dexcom if you need further assistance.
