Why can my friends can no longer send me tiktoks?

Multiple of my friends/mutuals have told me I no longer pop up under the "send to" option on TikTok. They have to actively search my name.

So far I've only heard this from my two mutuals who I have streaks with.

They can still message me normally and can send tiktoks if they search for me but I'm no longer listed under "send too" at all. One of the two people only has me and 2 other people added, it shows the two others but not me.
