Ionic run only syncing halfway - without the gps data!

So, I did a 5K run today, my Ionic tracked it perfectly with GPS etc. 

But when syncing, I get a half activity on my dashboard, with no GPS data.

I also apparently had 0 active minutes even tho the run was 27 minutes long. Absurd.

Anyway to get the activity to sync again? If I delete it from the dashboard, will it resync from the watch? Or is this just lost?

So tired of sooo many Fitbit problems, just the other day I had another activity that synced apparently ok to fitbit dashboard, but not to Strava and the TCX file is not downloadable.

Update: I seem to be having issues with syncing via my phone in general. It is weird, because notifications work, updating clock face works and steps and heart rate is synced immediately, but full sync with activities doesn't seem to be happening. I've done all the usual steps of disabling/re-enabling bluetooth, re-adding the watch to the app, rebooting phone and watch, etc etc.

Syncing via PC seems to work, tho my activity remains broken. Looks like I will need to factory reset to get phone syncing to work again.

I need to follow up my own post. How can sync on the mobile fail, but other activities between phone and watch still work just fine? I am still able to install apps, to change clock face, etc. It all works like a charm. It doesn't make any sense whatsoever.

But it will not sync properly. I click "sync now" and one of two things happen:

1. - the wheel spins for a few seconds then stops.

2. I get a red exclamation mark. 

No matter which, the sync does not go through.
