Humraah Collection review for TikTok

the recent tiktok app update push a bug, that my old business center created pixel is not connecting with the app, shopify send a pixel connection mesge, but tiktok app actually ois not connecting that pixel,, the new ad account created pixel is connecting, which is useless for us, we have almost one year data in that old pixel. and now we are facing this problem..... the app support team just said, we can't do anything in this situation, we have not the rights to do anything with the backend.
