@Truc1203 Adding one thing that looks exactly the same from the admin but is a completely different problem.
Go to Settings, Payments, then open Shopify Payments and click through to your payout history. Look at the individual payouts, not just the banner. If you see one marked failed rather than just nothing arriving, then this is not a review at all, its your bank rejecting the transfer. That happens when the account name does not match the legal entity on file, or an account was closed, or the details have a digit off. Shopify pauses payouts after a rejection and the banner it shows reads almost the same as a review banner. Different fix entirely, and its one you can sort out yourself in an afternoon.
If the payouts just are not there rather than failing, then its a genuine review and @lumine is right about how it usually goes.
Three things worth checking on your own side while you wait, because these are what stall reviews the longest:
The name on your bank account has to match the legal entity on the Payments account exactly. Personal account on a business entity, or a slightly different trading name, is the single most common thing that keeps one of these open.
The business type on file, individual or company, has to match how the store is actually operating.
The product categories you declared when you set up Payments should match what you are actually selling now. Stores drift over time and nobody remembers to update this.
Also get your document pack ready now rather than waiting for them to ask. Government ID for the owner, business registration if you have an entity, a recent bank statement showing the account name, and if you dropship, something showing your supplier relationship and that you can actually fulfill. When the request comes it usually has a deadline attached, and being able to reply the same hour instead of two days later genuinely shortens these.
Last thing, and this is the practical one. Set up a backup payment method now while you still can. PayPal or a third party gateway, added alongside Shopify Payments, not replacing it. Do not deactivate Shopify Payments during a review, that just makes things worse. But if this ever moves from payouts held to charges failing at checkout, you do not want to be starting a gateway application that day. Getting one approved takes time you would not have.
Your money is not going anywhere, its sitting in the balance and it all releases at once when this clears. Nine days is long but its within normal for these.
