How does TikTok still know my location even after I have a VPN?
I've been using a VPN for sometime now using Rethink on my Android phone, and recently I found a new Morphe patch of TikTok so I decided to give it a try and see what it's like. I was so shocked to see that every video on the For You page is from my country. (I'm connected to Mexico which is like on the other side of the world of my real country)
I know I'm properly connected to my VPN, and every IP detector like the one in Browserleaks shows Mexico so I have no idea how TikTok is detecting my real country.
I have no plan on actually using TikTok, I've not used it for two years now and I've alrrady deleted my account long ago, but this is still a problem! If TikTok can know my real country, then so can others, and by then having a VPN is totally useless.
Please, I need answers. Enlighten me.
P.S: Just adding in case it's important, that I was connected to a mobile hotspot when I tested this, because I have no mobile data.
EDIT #1: Tried it with the real TikTok app from the Play Store and it's the same result, unsurprisingly.
EDIT #2: It looks like it's not detecting my country when I use it on the browser though. (tested using Brave)
