Hello TParkev.
Welcome to Microsoft Community.
Regarding to your information I assume that you have some issues on viewing the PDF files.
May I ask which Apple device you are using? We were unable to reproduce your issue on our Intel-based Mac testing machine.
If you are able, you can try installing a Canary version.
Then try opening a PDF using both the Canary version and the regular version to see if the restriction still exists. It seems that there
may be some restrictions related to the Edge core. If the Canary version works fine, we suggest that you report this issue through Edge.
