Acrobat removed "Add files" option to the Share feature.
You need to add that back ASAP. As it is now, you can only share ONE file at a time.

This is a much needed feature that should not have been removed. We set up our monthly reviews to be done according to the features Adobe Pro DC offered up until the last update, we likely would not have subscribed to Adobe Pro DC had this not been available. Our members were able to easily access the files on the cloud and I was able to easily track who had viewed the packet. Sharing multiple files with either the "Invite People" or the "Get Link" functions worked so well, and I'm having difficulty finding a suitable workaround in time to meet tonight's deadline. Does anyone have a solution?
