high cpm and cpc in tik tok ads

Before a months i started my shopify store. i started also to run tik tok ads. they were working good and i had traffic in my website. after some warnings i got without any reason in tik tok i think they flagged me and now they are not driving views and also im getting high cpm.

at first i disconnected my tik tok account and i started a new via shopify also a new tik tok pixel. now im waitting to aprove this new account. Do you believe this will help?

What else should i do?

is it possible that wordpress and shopify can work together on a single domain? I want to integrate this wp site into shopify
