I can only echo what everyone else is saying. The app keeps losing connectivity with the speakers, roam being the worst. I uninstall then reinstall the app, factory reset all the speakers, get them all working from scratch. Then the next day some speakers are missing from the app again. I go to the customer support page and it talks about changing the settings in your "ios 14 device". I don't even know what that is, they're having a laugh! Total rubbish.
