Firetv is an Amazon product. Is your subscription to Watchnews.pro obtained through Amazon?
When you subscribe to streaming services through third parties such as Amazon, Hulu, Roku, etc., your subscription is with the third party, not with that streaming service. I don't know about Watchnews.pro, but for many services you can only then view them via that third party's platform,.
In general, if you want to be able to view a streaming service on several different platforms, you need to subscribe to the service directly on the service's own website.
