Garmin Connect v5.18 Breaks Fenix DND Notifications for Users

Garmin Connect v5.18 quietly changed how Do Not Disturb notifications work on the Fenix 7 and Fenix 6 series, and users are not happy. The update suppressed the classic alert behavior that athletes relied on during training and racing, cutting off a core communication layer between watch and phone.

For endurance athletes, DND management on a training watch is not a minor UX detail. If you are mid-interval or deep in a long run and your watch stops surfacing the right alerts, you miss splits, messages, or coach cues. The Fenix line sits at the premium end of the GPS watch market, competing directly with Coros Vertix 2S and Polar Grit X2 Pro, where notification reliability is expected at that 700-dollar-plus price point.

The community workaround right now is a downgrade to Garmin Connect v5.17.2, which restores the previous notification behavior. That is not a small ask. Rolling back an app version requires sideloading on Android or using older backups on iOS, and it creates its own risks around data sync and future compatibility.

Garmin has not yet pushed a patch as of this writing. This follows a broader pattern where firmware or app updates on Fenix devices introduce regressions, similar to the GPS accuracy issues that hit Fenix 7 units in early 2023. The brand's update cadence is aggressive, and quality control does not always keep pace.

Wait for an official fix before updating if you are still on v5.17.2. If you already updated, the downgrade is your only option right now. Not a disaster. But a frustrating own goal from a brand charging flagship prices.
