Hi,
Private library decks should be able to be accessed if they are included in a Group, and the other user has joined the group.
Let's take a look at your groups:
To get to this area, swipe left on a deck, tap "Edit", Export/Share, Shared Library, My Groups. Tap a group.
Do you see a "Password" filled out (it will show ****) for password if set. The is in the "Edit Group" screen. (Going into the password update screen will always show blank, as I don't know your password.)
If you don't see "****" for Password then there should not be a password. If you see a password and want to clear it, turn on "Clear Password", then "Save Changes"
I didn't think the app allows you to "search" a group anymore. You type the full group name or "alternate name" in the Group field when joining a group. Password should be left blank if group has no password.
Having said all this, I wonder if she has an old version of the app. Searching and "Group Code" sounds like terms from an old version. I would first make sure she's using a recent version of the app. This may be the problem.
If she does have an older version, I don't know off the top of my head if it just doesn't work anymore with my new library code.
If you still need help with this, I recommend you email me with the Group name and I can look into it more.
