Having problem attaching a pdf

I am using the latest version of emclient on Windows 10.
I use to be able to hit the little staple icon in the toolbar and attach a pdf file to the email. Now, it is inserting the text of the pdf in thr body of the email. So, the recipient of the email cannot open the pdf separately and print it out separately from the body of the email.
Has Adobe changed this?
Thanks,
Peter

Latest version means which version?

If this is with a beta, please send your feedback to testing@emclient.com, though I just tried it with 8.0.2531 and it works OK.
