Hi,
When you open a PDF in Edge, do you see the Adobe Acrobat logo in the lower-right corner? If so, check if disabling this Adobe integration resolves the problem. To do this, type edge://flags
in the address bar and press Enter. Search for the edge-new-pdf-viewer
flag, then set it to Disabled. You’ll be prompted to restart the browser and once it restarts, check if the problem is solved. If it doesn't work, then it's likely a bug and all we can do is to report it by pressing Alt+Shift+I.
