I upgraded to the new version 21 for Mac but my old version 20 was still there. I'm glad that is is because my jremote ap on my iPhone 6 and iPad will not connect with version 21 but will with 20. Any suggestions ? I would ultimately only like to have one version preferable the newer 21 that works with jremote and then how do I get rid of the old version and are two version taking up twice the data space ? Please help !!
