After a recent update (January 2022) this app and service has had almost zero issues with Chromecast Perfect timing for the Olympics. I almost exclusively use it with Chromecast. It used to be pretty iffy - like a lot of other apps. However, a day ago ads starting playing every minute during live broadcasts, so update my review from 4 stars. And Replaying videos sucks even more, ads interupt every 1 minute (bug probably), and the video doesn't return to where left off!!! Often can't scrub either
