Trying to add a PDF from Adobe Reader to Gmail. When I click the mail button it opens Gmail correctly but there is no attachment in the mail body.

I'm not getting any error message at all. The process seems to be working, the Gmail message opens up, but there is no attachment. I updated Chrome. I deleted and reinstalled Adobe Reader and Adobe DC Pro. I restarted the computer. It is a Mac running Big Sur.
