I just learned something very interesting. It's little tricky to explain but I will try

In this screen recording, X opens in a new inbuilt browser, as intended but NostrNet and the calendar app open as PWAs. 

Surprisingly, I never installed them, so how are they openning as standalone PWA. 🤔

It's like clicking an email link in your browser & your browser into an email app. It's makes no sense. 😅

It turns out, if your web apps share the same apex domain (e.g., note.nostrnet.work, cal.nostrnet.work), you can create a seamless flow between PWAs. 

I did it, and now it's live with the NostrNet web portal.🤙
