Hello everyone,

I can not unlock an object, that I posted to a board. I was invited to a board and I have editor rights, but can not see the unlock function. I understand that there is a long press on the lock icon to unlock an item but any long press is unresponsive. The piece I am trying to open is a 7 page pdf called Stephen Della Casa Works. See a screenshot of the front cover below. Any ideas would be great.
