I have same issue , and when I contacted Apple Search Ads they said They don’t accept prepaid card . I use same Prepaid Visa Card on search ads for years , and now I got renewal card but I can’t replace old one and save it . I use this card every where without issue even to buy ios apps from Apple Apps Store , but can’t use it for search ads !

still I didn’t get financial report for April 2021 . I searched on Google and found this post

You can't do any thing if they don't want this app in the apps store . Yes maybe there is a lot of similar games or apps in the store , but this will not help to get your app to be approve . They can reject any app for any reason or even if they just they didn't like it . So what we can do ? best advice move on in another project and new app idea ! that's my advice .

I received my payment today after waiting for two business days . You can contact Appstore connect financial support from app store connect page ,press contact and then send your details by the form .

Same problem here . I am from Bahrain and still didn’t receive my payment that paid on 2nd April 2020 . last month I faced same issue and I received the payment after 2 business days from the day of payment . before usually I received the payment on the same day of payment or next business day . But now for two months I am facing delay .
