MS Store Version is 1.16 and has a few issues that have already been fixed on the latest version. Sure I just uninstalled the MS Store version and installed from the site but if you are going to leave the MS Store version dusting might as well remove it =p
For reference my problem was with connecting/disconnecting devices FxSound would choose “blank” as the output device and mute the sound and did not actually add the new device to the list causing it to need to be restarted every time I connected my controller or turned on my TV (which I use as second monitor)
