Can I use the same store for a new Tiktok ad account in the US/Canada?

Hi,

I am based in the UK and have already began dropshipping here with Tiktok ads.

I want to dropship in the US/Canada instead of the UK now.

My questions are:

  1. Do I have to make a new tiktok ad account using a VPN? (I think this one is a yes)

  2. My main question is this one; can I use the same shopify store for the new tiktok ad account?

Appreciate it if someone could help. Thanks.
