Hi, we can see that PWA is appearing in your shared screenshot: https://shorturl.at/VYqLT . Kindly confirm exactly what pop-up you are looking for. Is this the kind of pop-up : https://shorturl.at/HxQ9q you want to show on your end?

ok I thought it can pop in the web page and didnt notice the address bar.

Another question I tried the demo site in firefox in my android phone, and nothing poped, including the address bar. It should support firefox, so I want address the problem.

Hi, kindly clear the cache from everywhere in your once including server side and retry.
