Are the subtitles in the grey box on the lower left auto-generated? Does that happen automatically?

Eh la la ça vole pas haut ça ... de plus en plus pathétique cette fille... elle veut maintenant un bébé à tout prix alors qu'il a à peine deux semaines elle détestait les enfants et disait qu'elle préférait se gâter... donc là elle veut un enfant d'un clown qui la trompe à ses 40 ans wow 😱

The “lunch in my city” trend. It feels so weird seeing a million videos of it and all of them have basically the same exact script They all talk about the same things in one way or another : they talk about how they’ve seen it all over their feed, then they explain how it works, then they say which restaurant they went to… Not to sound like one of them crazy woke ppl, but damn… this is pretty weird… And no one in the comments is pointing this out??? Am I onto something or on something?
Since yesterday my Tiktok has been kinda lagging. Videos don't play and if they do they don't play the sound. Slideshows aswell. Everything else loads but videos. Messages, comments, stickers, profile pictures etc. I'm going to contact tiktok support later down the line, but I'm asking if someone else has this issue currently
