why is tiktok on chrome browser and safari so buggy, its unusable

I never see the reposts section on my profile, only likes, favorites. And when I chat with someone, and then go to my profile, i dont see my likes or favorites appearing. None of them are loading. And often times, when i load the page it tells me i am logged out, but when i refresh the page, i am logged in as normal. They need to revamp the PC browser version. Started happening few weeks back.

The favorites show collections, when normally it supposed to show my favorites videos. Like all three sections should have many videos. The repost section never appears, so thats a long term bug.
