PDF Portfolio Sharing isue

[michael_3710]

Hi,

Our marketing person is having an issue where, when they send out PDF Portfolios made in Adobe Acrobat Pro as email attachments, when recipients try to open them, they get this strange page: 

The only way a recipient can open them is to download the portfolio and then open it. A very inelegant, confusing way for this feature to present itself. Is there some way to correct this? We tried it on Winodws 11 machines, fully patched, with fully updated Adobe Acrobat Pro desktop installations, and  Adobe Acrobat Pro configured as the default PDF app, with the Adobe Acrobat extension in Chrome.
