I am about to uninstal this app. Although it works OK on my Android devices there are problems with my Chromebook, Chromecast and HP WiFi printer. The Chromebook, connected with a Chrome extension, has been slowed down and usually does not connect with webpages. I do not seem to have a technical connection for Chromecast. I have found no guides to connect the printer. I can make things work from Android by repeatedly pausing, but the important problem is the Chromebook.
