Tiktok Ads

[AuroraNex]

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.
