Apple watch series 7 does not update although connected to charger and has 100% battery
I cannot update my apple watch, it is connected to power and has already 100% battery but when I press „install“ on watch app on my phone, it says that it has to be connected to power and has to have atleast 50% battery charged. My phone and watch are both connected to the same wifi. Phone has the latest software, I restarted both devices twice. I tried updating the watch from the watch not from the phone but didn’t work either. Don’t know what to do. Please help.
