What’s going on?

There’s something going on with the yellow favourite symbol, saves/collection on TikTok. When I press on the save button to put it in a folder, the save to collection screen, shown in the screenshot is smaller when it used to be larger. Idk why but the little thing and the scrolling to find the right folder is kinda irking me Ik it’s such a non-problem, just curious

Did my iPhone update? Is there a way to undo this thing and make it larger like originally? Is this a TikTok permanent update? For reference, my phone is in 18.6 update (idk what it’s called)
