Im getting the gateway error code "testmode_charges_only"

Ok I see what you mean now. I have two prompts on my home.

The first one reads

"Your Shopify Payments account is on hold

Your store can’t accept new orders with Shopify Payments."

The second one reads:

"Your payouts from Shopify Payments are on hold while we review your account

Contact Support for next steps on this standard review. This hold does not prevent your customers from checking out."

How do I get my Shopify Payments account off hold?
