To our great disappointment, the Mac OS X 10.7.4 update introduced a severe bug in iCal that prevents Spanning Sync from functioning correctly. This bug also affects other sync apps including BusySync and Blackberry Sync. It's unclear whether Apple intends to fix this bug.
Larry, Byron, and I don't want anyone paying for something that doesn't work, so we've decided to take the drastic step of temporarily suspending Spanning Sync sales. Of course, we'll continue to offer service to current subscribers. Once we fully understand how this issue affects the future of Spanning Sync, we'll post an update here.
We sincerely appreciate your support. Please contact us at firstname.lastname@example.org if you have any questions.
