2 stores + 1 fb ad account =???

[ali426]

hi dropshipper ,

I created my  first store ,it's one-product store but I didn't have any sales 

so I decided to create another general or niche store but the 

problem is I have one fb business manager account with only one fb ad account so what should I do??

it's ok if I unlink my first store's fb page from ad account and link new page 

or I should have new ad account .?
