Regarding

The WebApp is ignoring rotation lock on android

I found this:

https://stackoverflow.com/questions/77125890/prevent-screen-rotation-in-a-pwa-if-it-is-locked-in-the-os

I basically removed the "orientation" line from manifest - that solved the issue for me

If it works for you its fine that os what i said i have no plan changing just because of you sir.

As I said:

I changed the manifest.json and the browserconfig.xml and added a
different logo, that works fine, maybe you can add this as an option?

Why shouldn't this work?

I can not. Favicon is what pwa actually uses.

Idea:
Can you maybe add different graphics for Favicon and PWA?

For my PWA I use a logo with the site name in it, but that makes no sense for the normal Favicon.

I changed the manifest.json and the browserconfig.xml and added a different logo, that works fine, maybe you can add this as an option?

No idea as its requires in past for PWA installation.

One question:

Why is there a part for push notifications in the service worker, when OSSN PWA has no native push notifications?

I will check

I have an android with android 14 and WebApp through Google Chrome

The WebApp is ignoring rotation lock on android

When I activate the screen rotation lock, the WebApp is ignoring that

On other websites it is working, so it's a problem with ossn.

Guess that is handled through this component?
