You can also try this solution: Guide from Thoughtram

Short version:

 import { ChangeDetectorRef } from '@angular/core';
    ...
    constructor(private cd: ChangeDetectorRef) {}
    ...
    ... .subscribe( () => {
           
           this.cd.markForCheck();
        }

and you are good.

Background: when changing a value via .subscribe() angular does not notify that it should run changedetection. So you need to run it yourself.
