TikTok looks like an old version ? (tiktok shop gone)

I opened up tiktok today (in the US) to my feed looking different (scroll pattern is different, times two speed has white bars on the sides, no tiktok shop). Straight out of 2019. It asked me to log in to confirm my login too. I didn’t see an update in the app store. Anyone know what’s up? I tried looking if they got bought out but couldn’t find anything about it
