Fairbuds app cannot update Fairbuds

I just received my replacement pair of buds because the first pair was bricked by the bad firmware issue.

I spent more than one hour trying to set them up on iOS, but the firmware update process keep getting stuck at random percentage. I reinstalled the app, factory reset the buds, and tried probably 20 times, but I can’t get past the update screen.

I ask CS for a refund. I am never buying Fairphone products again.
