Hi Guys
I am using @auth0/auth0-angular library to integrate auth0 in the Angular application(version 9).
The session works fine but when we reload or refresh the page manually after some time approximately 30-40 user logged out and send to the home page. I have identified that token removed from session storage.
please help me to resolve this issue.
