Ionic App, silent Authentication or refresh token to allow user stay signed in

Hi there,

I just created a new Ionic app and using Auth0 for user login and registrations. I have .net core backend.

I am following the Ionic quick start guide and everything is working ok. I use new Universal login.

The issue I have is users get logged out after the access_token has expired. I previously used Silent Authentication and refresh tokens in two different apps, however I am unable to find a sample code like quick start guide for either. I have an angular website too. Hence my users can either use mobile app or Angular website to login. I would appreciate any help to keep my users loggedin, in both website and ionic mobile app please.

Many thanks
