Bakery installed on iOS homescreen redirects to Safari after login

[johannesh2]

Bakery can be installed to iPhone home screen and starts up correctly. After entering login credentials and pressing login button it opens up Safari instead of continuing to orders list view.

Check if explicit scope helps, right now manifest uses default

Also check if "start_url": "login", makes sense

I can't reproduce this anymore with the internal demo, but it still fails with the public demo.

Maybe it was fixed when merging #634, we can verify with next deploy to public demo

Turns out when the exact same .war file is deployed to a private app.fi instance, the issue does not happen. The only difference I have spotted is that demo.vaadin.com responds to the login POST request with 302 (Found) and Location: http://bakery-flow.demo.vaadin.com/ whereas my own app.fi instance responds with Location: /.

Note no https in the demo response: http://bakery-flow.demo.vaadin.com/

My current best guess is that Chrome on Android is not very strict in enforcing the PWA scope and allows handling this response inside the PWA as long as it eventually redirects to HTTPS (which does happen). And Safari is strict and immediately opens the browser as soon as the Location URL does not match the PWA scope.

Needs more investigation to figure out why demo.vaadin.com behaves that way.

Fixed by the service desk and Mikael in nginx config for:

• bakery-flow.demo.vaadin.com
• bakery-flow-spring.app.fi
