I have created two folders in 1PW on my MacBook. One folder is a folder of Smart folders, the other is a folder of login items. There are no problems with these folders on my MacBook. However, on my iPhone, I only see an unpopulated / empty folder of Smart Folders and I don't see the folder of login items at all. See screenshot. Sync over DropBox, which appears to be OK for all other items. I am using the latest version of iOS 1PW on an iPhone 6+.
1Password Version: 5.4.2
Extension Version: Not Provided
OS Version: 10.11.2
Sync Type: DropBox
