Thanks for all the help with Github. I really appreciate that.
Since I am a fan of helpful discussions on the core topic, I wanted to get this discussion back on track and sum it up for potential future readers:
Currently, there seem to be problems with the third-party launcher KISS when installing PWA and/or adding shortcuts to the home screen.
Since these problems do not occur with the standard GrapheneOS launcher, I assume that the problem lies with KISS.
There are already issues on this topic on Github, such as this one:
https://github.com/Neamar/KISS/issues/1792
I have (tried) to open an issue with the following content:
Describe the bug
Not able to "add to home screen" or "install app" of PWA from Brave or Vanadium for sites like Twitter, Duolingo etc.
Shortcut also doesn't show up in search, although "KISS settings> search settings> Shortcuts" is enabled.
Installation of PWA and adding shortcuts to homescreen on stock launcher works flawlessly.
Seems to be similar to issue #1792
To Reproduce
Steps to reproduce the behavior:
Go to PWA's website
Click on three points> install app
confirm dialogue with "install"
Pop-up shows up saying: "installing "
Expected behavior
Shortcut PWA should be visible on home screen or searchable in KISS search.
Additional information
App version: 3.21.0
App installed via: Play Store
Due to shadowbanning on Github, I unfortunately seem to be the only one who can currently see this issue - everyone else gets a 404.
If the account is un-shadowbanned, I will update this post.
Otherwise, someone who is experiencing the same problem with KISS having a Github account is welcome to save themselve some work and copypaste the mentioned issue.
@matchboxbananasynergy if you want, you could remove the "Vanadium"-tag as it now becomes clear that the bug has nothing to do with a specific browser.
