UPDATE: 6S problem resolved. PhoneCopy is back to five stars. Worth every penny and more.
PhoneCopy used to be perfect. But after getting the new iPhone 6S and updating the iOS to the latest version, Ive experienced a weird issue. I use my iPad as my "master" Contacts list and then export the list to other devices like my iPhone (Server To This Device). So, after Ive sent the latest Contacts to the server and then get the updated Contacts from the server on to my iPhone, everything looks great and all the data is there. Sometime later, Ill look for a contact on my iPhone and some are no longer there! For example, Ill have 1700 contacts on my iPad and the server, but only 800 on my iPhone. This happens even when the app is closed. This is a bizarre problem.
I use my Contacts app extensively for a wide variety of information, much of it, impossible to obtain again. Therefore, PhoneCopy, for me, is indispensable. This is a five star app and well worth the annual fee. I just hope they can identify the problem and correct it.
