Hi @axel.valadon , sorry if my replies irritated u.
Just get a bit annoyed when ppl say wfs has a bug when its work just fine for me. But i understand some bugs are wierd as it show up to some but not others. Its due to logic flow so if u hit the path the bug will show up.
So sorry about that.
Anyway if still unable to get your wfs to connect to your watch. This might help u mitigate the issue for now.
