Doesn't work. Doesn't connect. I tried to contact customer support, but they take days to rrspond (email only). When they did finally respond, their instructions didn't match options for settings on my DS1. I submitted request for clarification and am still waiting for a response. Being able to access my files is the main reason I bought this rather expensive system. The app is useless.

Used to work great, now it's completely broken. just constantly says connected and then reconnecting. Photo backup doesn't work at all becuase of this. Also when photo backup worked it couldn't find some of the folders on my phone where my older photos were stored. so some are backed up and some are not. Even manually trying add the folders doesnt work. NAS is great, but god you guys really suck at software. Every app is a dumpster fire.

I'd like this app a lot more if it didn't have these ridiculous, frustrating failures of logging in. Even worse, is the part where the automatic photo backup rarely works, at all, and even when it sort of works, it's *never* automatic (have to open app & log in). Also, the backup function inexplicably requires you to log in, even though you're already logged in, but mostly it just returns an Error/Connection Failed status on the backup, and no amount of resetting or restarting makes a difference.
