Browser Refresh button in the Ionic Conference App?

Maybe a problem linked with the Ionic v3 router which gonna be solved with the new v4 routing system?

I’m right now trying to build a PWA with v3 and I face kind of the same problem. Right now to solve it a bit I have set my nginx to reroute everything to root also set the following strategy to remove hashbang in the url in app.module.ts

IonicModule.forRoot(MyApp, {
   locationStrategy: 'path'
 })

But still, I think I do face the same problem too, specially when I run ionic serve

Don’t know if my comment helps but if I understand correctly what you meant, just to say, you are not alone
