Report Sync Pro Randomly Deleting Files in Sync Troubleshooting Posted January 26, 2017 14 minutes ago, Devonavar said: Did you ever resolve this? Nope. As you can see above, Sync Support asked me for more details, then never responded when I provided them. Sync randomly deleted files again after that, so I learned two things from the experience: 1. It wasn't a fluke. 2. Sync Support doesn't support their customers. We had to drop Sync Pro and go with a much clunkier system involving Dropbox and system-to-system synch desktop apps. The system is no where near as elegant as Sync Pro, but 6 months later, we've yet to have files suddenly disappear.
