Current behavior

Working on an app I'm using Angular 10 (not supported, I know). While testing on Safari 14 everything works fine. SignOut leads to signed out user. But with current Chrome and Firefox, the signOut Method doesn't sign out.

While analyzing the problem, the finalize() part in signOut() Method is never called on Firefox and Chrome. In Safari it is executed properly. I don't know why at the moment but I will try to investigate in this.

Expected behavior

User should get signed out.

I've had a look at the code and found https://github.com/neroniaky/angular-token/blob/ff911a81080285e8b19939f56c7fb5d7f0ac46e7/projects/angular-token/src/lib/angular-token.service.ts#L363

signOut() returns an observable, that is never subscribed. The interesting thing is, that this seems to work on Safari and obviously on older versions of angular. Subscribing at this point shouldn't be a problem?
