Here’s the quick scoop: Garmin Connect appears to be having iPhone sync issues tied to a recent app update, with some users reporting that their watches were disconnected or stopped syncing properly. Reports also suggest Garmin has rolled out a fix in version 5.21.1, but it hasn’t fully resolved the problem for everyone yet.

What people are seeing

  • Users say Garmin Connect is failing to sync workout and health data from their devices.
  • The problem seems linked to the latest Garmin Connect 5.21 update.
  • Available reporting suggests it may mostly affect iPhone users.
  • A follow-up fix in 5.21.1 has started rolling out, but some devices still are not reconnecting cleanly.

Forum vibe

Garmin’s own community forums are being used by users to report the issue and compare workarounds, which is usually a sign the problem is widespread enough to be drawing a lot of attention.

What to do

  • Check whether your Garmin Connect app is updated to the newest version.
  • If your watch disappeared from the app, try re-pairing it.
  • If you’re on iPhone, be extra cautious about updating until you know the latest patch works for your device.
