Hey, we finally overcame this issue
we fixed this by following this previous topic
The issue was of bundling and polyfills. We basically have to copy some files from node_modules and inject its src in our index.html
The funny thing is that I myself made the changes as described in that topic but I guess I didn’t do it all the way.
Today another developer did it and it just worked.
Now we have another problem that is that device back button is not working.
