I can sync fine with Strip on my iphone, ipad, and pc Win 7 using Dropbox. However in Strip for Win 7, as soon as I begin to edit a category or entry, the “Sync” button grays out & becomes un-operable. I must close Strip, re-open & log in to be able to sync. Is this normal? I can get around it but it is annoying as I’m doing a lot of editing & syncing amongst the three devices.
