Created attachment 471673 [details] Error URL We are using Webkit to launch our UI and it has attachments(image/pdf). On download of attachments we get blob URL(blob:https://a.com/906fc2ec-6098-4942-b44b-bfcc94d298af) and on click it should open file. This is working fine in versions iOS 17.0 and below it. In version 17.1, 17.2 - we are getting this error - WebkitBlobResource error 1. There are no changes in our code and same flow is working fine on Android/Web. This has impacted attachment functionality on all latest iOS devices. Requesting any updates/fixes went with latest release which could break support of rendering blob URL in Webkit?

@Hanisha - latest released is iOS 17.5.1, can you try this and also can you share website or app name, from where we can reproduce this?

Try downloading uploaded file and click on downloaded file to view 6. It will open file with Error - WebkitBlobResource error 1.

Thanks for reporting this issue. The underlying cause appears to be the introduction of partitioning Blob URLs by top-level origin (e.g., https://cards.vap.expedia.com): https://webkit.org/blog/14787/webkit-features-in-safari-17-2/#privacy Therefore, this is expected behavior, but the breakage in your app is unfortunate and not desirable. We're investigating solutions.

Hi Team, Any further update on this? Requesting ETA for resolution as it is blocking our users from downloading attachments.

I'm currently porting Tampermonkey to the Safari WebExtension API and encountered this issue as well. In my case it helps to go back when the error page is shown and try again. The download then starts as expected. 🤷
