PDF preview in Gmail broken

[kcalderw]

Is anyone else seeing issues with clicking on a PDF in gmail and only the first page (or nothing) will load? It's been going on here for a few days. If you download the PDF, it's fine.

Seems fine here (Chicago area)

[kcalderw]

Yep it's not just me either. It seems to be happening to a number in our domain. Any chance the changes to DMARC would do this?

Nah, I've had DMARC for years, and no adverse effect on PDFs.

I am seeing this also.  What filter do you use?  We have Securly?  When I am on our normal Wi-Fi (Windows Securly DNS filtering) it is not working.  When I switch to the guest it starts working again.  I am not sure where the issue is yet just starting to try and figure it out.

@kuhnd You might want to open a ticket. I did and they confirmed there was an issue. They fixed it (on their end) and we seem to be fine now.

Just tested at home and it opened all 4 pages in the preview.

I don't have Securly DNS (you should talk to them), but I do have a pihole that blocks things quite aggressively, and uBlock Origin that blocks things in Gmail.

Others are having the same experience over in MacAdmins. don't know if they are in Education.

And just now it happened to me. 😞

Reloaded the entire Gmail window and opened the email again.

This time the PDF loaded all 4 pages without issue.
