[Bug]: Download share sheet does nothing on iOS Safari (works on desktop)

[nanhoes]

What happened?

Downloads work fine on desktop, but on iOS (Safari and installed PWA) tapping the "Open iOS share sheet" button does nothing once the file is ready. The page briefly shows an "Opening file" indicator and then nothing happens, no save dialog, no share sheet.

Environment: self-hosted via docker compose, latest images, iOS Safari + standalone PWA, desktop Safari works fine for the same download.

Steps to reproduce

1. Tap Download
2. Tap Start download
3. After download is ready tap Open iOS share sheet

Expected: iOS share sheet opens, or a save prompt appears
Actual: Briefly shows "Opening file," then nothing happens. No error, no share sheet, no save dialog.

Hello! I'm on it :)

Thanks for the report.

I pushed a fix for this in #124, but I’ll keep the issue open until you can confirm it works on iOS.

The old button tried to open the iOS share sheet directly after the file was ready, but Safari/PWA can silently ignore that. I don’t have an iOS device to test this properly, and I also didn’t find much useful documentation around this exact Safari/PWA behavior, so this is my best fix based on how iOS usually handles user-triggered file opens.

The new flow shows a normal Open file button once the artifact is ready, then opens the artifact URL directly from that tap.

Can you test it again on Safari or the installed PWA when you can?

If it still fails, please tell me:

• iOS version
• Safari or installed PWA
• what happens after tapping Open file

I think this should work, but I’d rather keep the issue open until it’s confirmed on a real iOS device.

Thanks for the quick fix! Can confirm it works properly on safari but does not work on PWA.

• iOS version: 26.2
• After tapping Open file, seems to open artifact URL then redirects to about:blank page
