Hi @drz, sorry you haven’t had a reply from us yet. Could you try updating to the latest version of STRIP on both your Mac and your iPhone? The last couple of versions are sync compatible with the latest versions, but I don’t think 2.1.1 on the Mac is sync compatible with the latest version of STRIP on iOS. That said, I’m not entirely sure this problem is related to sync as much as it might be an issue with an older version of the iOS app running on the latest iOS. Could you give the apps an update and let us know how it goes? The latest version of STRIP for OS X supports 10.7 Mountain Lion, so I don’t think you should run into any compatibility issues there. Thanks!
