Can't share a pdf from CC mobile to external client

Hi folks

Im struggeling with sharing a pdf file to a client. We are a group of co-workers with acces to the same File area on CC Asset.

Neither me (the owner) or the others can share pdf files to external people from mobile devices.

When we use the share option from the devices, CC convert the multiple-page pdf fil to a single page jpg, containing the frontpage only...?

It is very relevant for us, being on-site with the client, to be able to send a specific pdf file from the parent folder, immediately.

At this point I have no solution, other than to use dropbox instead?

Thanks in advance.
