How to download Tiktok now?

My sister deleted tiktok after it went dark. Now that is is live again, she can’t download it again since it’s still blocked in the app store.

Luckily she is abroad so there may be some loophole for her to get it back. Does anyone know any? I have suggested her change her account location but she may lose some purchases. Also have heard she may need a VPN to access it.

Any suggestion is helpful!
