App needs some work – Sync - Secure cloud storage Review

Listing directories and downloading files keeps getting slower and slower. In fact, I can’t even download anything at the moment. It just hangs forever on two iOS devices. Net connection is good. Sync between Macs seems fine. Seems isolated to the app. File integration on iOS is hit or miss between versions. Sometimes it works... other times it doesn’t. There are times where I’ve even lost data trying to save a document in Excel. I have to open a copy of the file in Excel, then copy it back to sync to be sure I’m losing any data. It’s really too bad, this service is otherwise awesome... it makes zero knowledge cloud storage very easy to use. I hope the mobile app gets fixed soon!
