Nick here from Shopify.
As per the banner in your admin, your Shopify Payments are on hold for some reason. We’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback. Please visit our support team here and log in to your account to create a support request. Once you are talking to a support advisor and verified your account they can assist you with this.
Or if you already have an open support ticket with the team about this, you can continue the conversation with them there.
