I love WTOP, I hate this app – WTOP - Washington's Top News Review

There used to be issues with this app a while back, such as the live stream not working. This was working well for a while now. Fast forward to the September 2017 update, now the app doesn't work, AT ALL. When I click to open the app, nothing happens, how can I revert to the previous version?
