Triggered auto assignment to @RachCHopkins (Bug), see https://stackoverflow.com/c/expensify/questions/14418 for more details. Please add this bug to a GH project, as outlined in the SO.

@vincdargento can you please define "large PDF attachment"? What size is this?

[vincdargento]

@RachCHopkins This is the large PDF we usually use in our daily testing:

LARGE PDF FILE.pdf

[RachCHopkins]

Ok, it's 5.5MB. I will try using a different file just to rule out file issues.

[RachCHopkins]

Repro steps not great - Step 3 is go to iPhone settings, apps, Safari and "clear history and browsing data"

Account used: rachytestrach+0403@gmail.com sent to rachytestrach@gmail.com

After clearing cache, recipient shows as "Hidden". But can't repro the issue.

Tried again, different recipient. Still cannot repro.

Using file which is 4.7MB

Resource Management Act 1991.pdf

If I use the test file you provided @vincdargento , I get this:

(Same as you)

And if I use a whopping file (10MB)

91474-exp-2023-merit.pdf

I get this:

and then if I refresh, it loads:

Can you try with my files, and just rule out that one file as being a problem?

@RachCHopkins The tester tried with the PDF file you provided, is also crashing (iPhone 15 / iOS 18.3.1):

Screenrecording.03-13-2025.09-21-07.1.mp4

I tested myself with our large PDF, I am getting crash issue too (iPhone 13 / iOS 18.3.1):
