I noticed that several people on here are having trouble with the app, so I decided to try a few different versions. None will connect to spotify playlist that I tried. However the older one's do not require downloading additional resources for smart jam or quick jam. All except the latest version will not download these resources. You click download and nothing happens. Out of the one's I tried, I prefer 2.2.2.4195 released in december of 2021. I like the icons better in it than the newer versions. It appears to have all of the functions of the later versions but appears more stable and no additional resources needed to be downloaded for smart jam and quick jam to work. I believe these bugs are a result of PG trying to incorporate the app with Spark Live. Just a guess. But updates are not always a good thing. Look how many times microsoft released bad updates over the years. I turn them off whenever I do a clean install of windows. Don't want em. But I plan on using this old version until it stops functioning. Don't forget if u uninstall the app to try an older version you will lose any presets u have previously downloaded. So u must back them up to the dropbox cloud and restore them after the app is reinstalled.
