Sort of ... but I have used TeslaTV in the browser to access video sites acceptably e.g. iPlayer in the UK ... it even does Youtube probably better than the built in app. I'm not saying it's fabulous but probably not much worse than a cobbled together TikTok app. I should think that the main barrier to TikTok in the browser (having just had a look on my laptop) is that they go out of their way to push you to their app ... repeatedly ... which would probably make the any browser experience pretty miserable!I am sure you know the web browser in Tesla is the least likable experience in the car.
