I have a team account. I added another coworker as non licensed user and gave them editing and sharing privileges to a sheet. I then created a roll up sheet which narrows the main sheet down to things assigned only to them. I shared the roll up as well with the same privileges. The coworker can't edit the cells (specifically a tick box to mark this as completed) or add comments or attachments to a row in either the main sheet or the roll up. They are supposed to be able to with editing privileges set correctly. Any advise on why this isn't working????
