I had a YouTube video paused because it went to get some snacks. When I came back, my hand or full of snacks so I didn't have fingers two tap the play button. Instead I asked Google Assistant to "play the video" which is the exact sentence that I used, and for some reason Google Assistant did not understand that's I wanted the video that's right on the screen to start playing. Instead Googke Assistant started playing a random youtube video. Google assistant could be very useful at times, but there are also some small, seemingly convenient commands that it doesn't understand. Same goes with Bixby. I do know this is a Google thing, but because this applies with Bixby as well, I thought it would make sense to post it here. Just to add, I know that Google assistant nor Bixby would respond to voice commands when any video is playing because it's trying to avoid videos that has the trigger phase in it or phrases that sounds similar to the trigger phase.
