Bug: Portfolio - when opening file it opens blank in protected or unprotected view
Steps to reproduce:
Open up any Portfolio then either double click on the individual PDFs within the portfolio or click on the "open file" button up top then when you open it, it will be blank.
Environment:
Edition Windows 11 Enterprise
Version 24H2
Installed on 2/9/2026
OS build 26100.8875
Experience Windows Feature Experience Pack 1000.26100.334.0
Expected result:
The PDF within the portfolio opens in it's own tab and actually shows it's contents to be worked on.
Observed result:
When opening a PDF within a portfolio by either double-clicking the PDF itself or clicking on the "Open File" button in the top-middle of the screen it opens the PDF but it is blank with nothing shown. The only workaround is to:
- Open Adobe Acrobat Pro.
- Go to Menu or Edit > Preferences.
- Select General.
- Uncheck Open documents as new tabs in the same window.
- Close and reopen Acrobat.
- Try opening the PDF inside the portfolio again.
It will work but will be in its own separate Adobe Acrobat window covering up the Adobe Acrobat window that contains the portfolio you opened it from. I do not know if there was a recent update or something but until just a few days ago this never happened to me on any portfolios. I even tried changing the security/protected view settings to no avail.
