Garmin Smartwatch keeps disconnecting from Garmin Connect App on iOS

Hey Everyone,

I recently switched from using Android to using an iPhone 16 Pro.
Quickly I noticed that my Forerunner 955 Solar and Phone didn't stay connected after closing the Connect App on my phone.

Steps to Reproduce:

  • iPhone 16 Pro
    • iOS Version: 18.1 (22B83)
    • Garmin Connect Version: 5.7.1.2
  • Garmin Forerunner 955 Solar
    • Software Version: 20.32 [DFU-44be53]
  • Location
    • Germany
  1. Connect  Watch to Phone via Garmin Connect App
  2. See it working nicely as long as the App is opened. (Sync & EVERYTHING works)
  3. Close app and instantly see the Phone icon crossed through on the watch

Notable behavior:

  • Notifications are STILL delivered INSTANTLY to Watch on Reception
  • Notification History IS visible on Watch
  • Watch is ALWAYS shown as "Connected" on my Phones Bluetooth tab
  • Calendar does NOT work
  • "Find my Phone" does NOT work

Steps taken to fix this issue without resolve:

  1. Removed and re-paired the Watch to the Phone in Garmin Connect App (also removed from Bluetooth tab before reconnection)
  2. Restarted both devices (tried before and tried after first step)
  3. Could not update Firmware or App since they're on the newest version. (Watch Version Update was checked on Garmin Express on Windows PC)
  4. Gave the Garmin Connect App an "Always" Location access + Step 1 & 2

Does anybody have some recommendations on how I can fix this issue or is this just the way that it's gonna be from now on on an Apple device?
