Much like other apps on your phone, certain app features and functions require an internet connection! If you don’t have wifi or cellular coverage, you won’t be able to do things like:
- start a session from the app
- adjust the temperature level in the app
- change your preset sessions
So while an internet connection is important for certain features, you are still able to use your Wave 2, by manually pressing either the dotted or the blank button to start your most recent session on that side.
