Not all Files Synching to iPone


I’ve been using CM with Google Drive between my Linux and Windows machines with no problems for several months now.

Earlier this week, I purchased the IOS app and set it up. Thing is, not all the files show up on my iPhone. For example, I have a folder called Pictures. There are 9 pictures and I see them on both my Windows and Linux machines, but on my iPhone, the Pictures folder is empty. I removed and re-connected the vault - same result. I uploaded a picture from my iPhone to the Pictures folder and it shows up on both desktop machines, but that is the only file that shows on my iPhone.

I have no idea what else is missing on my iPhone.

Any suggestions on what do I do to fix this?
