hello,
i am experiencing the same issue even with the advice above. when using the phone under Bluetooth internet access i click the toggle and get “cant use bluetooth tethering while connected to wifi network”. then i turn wifi off on the phone, but when the toggle is clicked on, it immediately turns itself off with no error.
from the watch i navigate to settings > connect > bluetooth > paried devices > select my phone > system cog wheel > doesnt even have an internet sharing option to click???
