Suunto 9 Baro can't Sync activities (Redmi note 8)

[Foot Mezel]

Hi,

I recently bought a S9 Baro and sadly the watch has big troubles to sync my sport activities. It worked 3 times and then, strangely, it suddenly doesn’t work at all. The sync begin, it shows “POI” and then “1/1 activities”, it takes a long time (1 min maybe) and then goes to the rest like “GPS accuracy” and then at the end it’s written that “There was an error by syncing, try again ; 1 activity couldn’t be synced”

So my activities are detected but that’s all.

I tried everything, resetting both, pairing, unpairing, rebooting both, nothing worked.
And same problem when I tried with a other smartphone (Honor Magic5 Lite).

Any ideas ? Is it a known issue ? At least, is there a possibility to upload my activity with an other app or directly to the PC ?

Thank you
