Unable to open PDF Files with the new Microsoft Edge

(I’m just some guy not CH) I just tried using Microsoft Edge 38.14393.1066.0 / Win 10 Home 14393.1358 - it seems to work for me (trying several different documents). For example I accessed the CH Beta site and tried as an example:

Company number SC294759, filing history entry for 21 Jul 2015 (accounts):

https://beta.companieshouse.gov.uk/company/SC294759/filing-history/MzEyNzQzMTY5OWFkaXF6a2N4/document?format=pdf&download=0

This will open something like (may change for different accesses?):

That PDF opens OK in Edge.

Edge settings are: don’t block cookies, block popups. IE is apparently not using plug-ins for PDFs etc. I’m behind a firewall.

There has been a particular issue (corrupt XREF block) with particular PDF files but there was a fix for that quite some time ago. Someone did query that a while later however so maybe have a look at those investigations to start:
