Watch stuck in activity sync / "not connected" loop
-
My Ocean seems to be stuck in a disconnect loop whilst syncing new activities.
There are 3 dives logged from yesterday on the watch – it starts syncing with the app, gets about a quarter of the way through the first activity, then shows “not connected”, resets and starts again. Seems to be in an endless loop, going on for several hours now.

For a split second before showing “not connected”, the app screen shows “watch updated needed” – however the watch is up to date, running 2.40.56. The app is up to date too from the app store (iPhone 17 Pro).
Strangely, there was a very short auto-logged dive that did sync to the app (I have since deleted it from the watch), so a sync did work at some point yesterday. I can still see that activity.
I’ve tried powering off the watch, and also unpaired it from the app and re-paired it, but same behaviour. Any idea how to resolve this?

@garethm This is a problem specific to the iPhone 17Pro and a new BT chip. Apple states they will fix and this is an Apple issue. If you have an iPad I would sync to that temporarily and you should be fine.

@Brad_Olwin it’s happening to me too on an iPhone 17 (non-pro)

Confirming I was able to sync succesfully after pairing the watch back with my prior device, iPhone 16 Pro.
I will note that one very short dive (like 5 seconds) did sync via the iPhone 17 Pro. But the longer ones would not sync.

@logger All the 17 phones have the new chip….

I saw the Suunto in-app message that this issue was being worked on, and subsequently that it was resolved – however I’m still unable to sync new activities to my iPhone 17 Pro. The app seems to be up to date (auto update is on, no App Store updates are showing).
The Suunto app still resets back to the initial sync state every few minutes. It seems to be a bit less disruptive than before; the watch does not show as disconnected intermittently – but it does still reset and activities do not sync. I tried leaving it syncing for a few hours, no joy.
I have a few scuba dives logged on the watch, followed by a hike – it never gets past 1/3 activities syncing.

@garethm do you use vpn on your phone?
I have had issues with syncing on my Pixel phone when using vpn. Solution was to exclude the Suunto app in the vpn settings (i.e. vpn is not used for Suunto app).
Edit: I now read the whole thread and I realized that the issue seems to be related to latest iPhone model. Anyway, I will leave my info here in case it helps someone else.
