PWA not being installed on any browser
PWA does not work on any Android browser I testet (different from the initial Zap implementation by Mike).
In Zap, Chrome is the only browser I can actually "install as an app" and have it work as a share target from other Android apps. FF, FF beta, Fennec, duckduckgo, etc. do not seem to support it yet => "add to homesceen" option only, no install, no app in drawer, only bookmark with Zap icon incl. browser icon overlay, no share target from other apps. I'd love to use other browsers, but I understand this has to be attributed to browsers' implementation, not Zap.
In Hubzilla 6.2 - again only for Chrome Android - I actually see the same "install as an app" popup as in Zap - but when I click "install", a new popup comes up asking if I want to "add to homescreen" - again: no install, no app in drawer, only bookmark, no share target.
So in Hubzilla, PWA does not work in any browser, although it works in Zap at least on Chrome.
I know there has been a lot of discussion in the support channel, but I am not sure if participating actors have experienced a real working PWA installation in Zap via Chrome to compare it to. They seem to be happy with a bookmark opening a dedicated browser window.
