Unfortunately, it doesn't look like you can watch replays on ESPN+ through either Roku or a SmartTV menu without a risk of being spoiled. Watched a replay of a Euro 2020 qualifier last night and the icon you need to click on to start the replay has a picture of one of the teams involved celebrating a goal! At first I thought, surely they're just showing a well-known player celebrating a goal from some random previous match. But, no, it was from this particular match! Then one wonders how big is the spoiler? Are they just showing a picture of a random goal celebration from that match (already a big spoiler in a sport that average under 3 goals per match, mind you), or are they showing a picture of what essentially sums-up the entire match - one of the winning team celebrating?
