5 stars: App works well, apart from a few glitches once in a while, but those are rare. I am so happy that they finally offer the commentary for alpine skiing in English outside of the UK (ad-free broadcasts). That was the worst decision ever when they stopped offering English commentary in NL. So glad that it's back! I cannot comment on the other programs as I only watch the skiing, but the coverage of that sport is excellent.
5 stars: Initially I had a streaming issue with the app. It had a glitch in conjunction with Apple tv. It would jump backwards about 15 seconds, every 30 seconds, and replay what you had just seen. The issue has been resolved and It is working well now. The sound and picture quality is very good.
4 stars: Excellent channel. However, one could up the video quality and reduce the glitches, especially the lagging, not caused by my provider nor my devices. More tennis please.
3 stars: Panel timeout too long. When starting a stream say snooker match the timeout on the panel appears for too long before dissapearing. It's there for 10 seconds. Could this be recuded to 5 seconds as its in the way of the scoreboard?.
3 stars: Different streams for same event but different languages are available for each, 4k missing, horrible ui to navigate videos.
2 stars: Horrible UX. A few ideas to explore: manage interests, have a watch history, show categories (tennis / mens tennis / solo), mark future events to watch (with notifications before start), ...
