My WD MyCloud failed recently so I decided to use a Raspberry Pi 3 and OMV in an attempt to replicate the MyCloud's features. So far I've managed to get the NAS side of things working fine for viewing content on various devices (laptop, smart tv, phones, tablets, etc) but I can't figure out how to upload pictures directly from my iPhone to a selected folder in the NAS.
I've got the File Explorer Pro app and that's great for viewing the content on the NAS (it can also add new empty folders, copy files onto the iPhone, and delete files/folders) but it seems unable to actually upload anything from the iPhone itself. I also purchased the PhotoSync app because I thought that would do it but I can't figure out how to get it to work, it's mostly just long loading screens with no directories found. I might just be doing something wrong when I input the NAS port or directory details on the FTP settings as I'm very new to all this so forgive my ignorance, but any help would be appreciated.
