The app is just horrible. For years I constantly have to re-set one soundtouch system out of 3 in addition to the wave. Right now the app tells me there is an up-date but there is no way to up-date. If I click on "remind me later" the up-date will reminder pops up after 3 seconds. Hoing on for years One time we had to be on the phone with Bose support for hours and everything had to be re-set And reading through the reviews many are having the same trouble with this app and nothing changes.
