Exactly. She didn't go on various variety shows alone for nothing. It's not like she's the most popular member and they just had to invite her because she was super famous anyway.
AAt first, I thought, 'Oh, maybe since she's already Mucore's MC, they want to show more of other members,' but this never happened with Tiff, just her. With Tiff, it's normal, some active eps, some invisible eps. There was this clip from the last ep, where the tall team was cheering for Tiff and you can see Yuri there, then they switched to the short team cheering for Hyoyeon and you can see that Hyo's opponent there was actually Yuri and not Tiff, yet they never showed Yuri in that game. Then she won some game before (I don't remember what game) but in the next game, she just got that big X shirt on. WTH?
It was such a waste. She actually seems very close with Hyeryeon and Seyoon too, but I guess we've bare ever seen that on the show. Funny how I got too see more of her interaction with Hyeryeon on some 1-hour show than in 6 eps of "her own" show.
