Note that to change the preferences for a Family or Friend for photo sharing you need to do it on the computer and not the app.
Also, who ever bought the MM will have the rights to download. If you bought then you will need to give your friend your log in information so they can edit pictures and download to their computer.
Edits can only be seen on the account they are done on. So all edits need to be completed under the user account of whomever bought the MM. This was a 4 hour mistake on my part so I wanted to put that out there.
Make sure that all the pictures from your friends account show up on yours or vice versa. The total number of photos on each account should equal (before edits). If they don't equal something is wrong. Call photopass help if this happens. They were extremely helpful this past trip as a few hundred photos weren't transferring between accounts. Ended up being a ticket issue they had to go through all the photos one by one to see what was missing and reassign to another magicband on my account.
