Confirmed on BMW PWA in 120 on a Pixel 4a.

STR:

• Install BMW PWA
• Navigate to Reach Regulation in footer area of page
• Select a PDF of the regulations in the app

This is most probably due to the site trying to open the PDF in a new tab ( target="_blank" set). Custom tabs should have the same problem.

The bug can also be reproduced when opening a Custom Tab, which can be very frustrating for users opening a ticket they received by email. There's no decent workaround (apart from copying the link URL from the email, opening Fenix and loading the URL from there).

STR for PWA

• Open https://pdf-redirect-issue-repro.onrender.com/pwa on Fenix
• Add to home screen as an app
• Open the PWA from the Home screen
• Click Load PDF

Expected result:

• a PDF is loaded

Actual result:

• The page doesn’t load

Alternative to https://pdf-redirect-issue-repro.onrender.com/pwa:

Clone https://github.com/titooan/pdf-redirect-issue-repro and run:

python3 -m venv .venv && source .venv/bin/activate && pip install -r requirements.txt
python pdf_redirect_server.py --port 8765

Access from Fenix, but you might not be able to install the PWA because of the lack of HTTPS
