There’s no animation to scroll through discussion cards. It always displays 3 cards regardless of the query and the third one extends beyond the page causing horizontal scrolling on the page itself. This doesn’t happen with news and video cards. I’ve only tested this on mobile and am not near a computer so if anyone on a pc can try it out, please post below if the issue exists beyond mobile.
Behaves similarly to how news and video cards are displayed where if there are more than 3 relevant discussions, you’re able to scroll through them.
