Apple watch complication not working

Hi, I am trying to have some sensor values (temperature data) on my apple watch. I have created some apple watch config (complications) in the companion ios app but when I try to add it in the watch ios app I have only something called “espace reserve” or “space booked” or “space reserved” (in english) instead of the complication I have created in the companion app…
Any idea of the issue ?
Thanks a lot for your help.

Hi, nobody has a apple watch and wants to use it with HA? I have tried to follow this… https://community.home-assistant.io/t/apple-watch-complications-and-widget-help-needed-how-to-start/240208/2 …but it is working only for a “color” face. Any idea how to do it for another face ? Thx
