“Currently unavailable” listing even though I have stock in the inventory.

New seller, selling via FBA.

My product has been listed on Amazon for a couple months now with no problems, I even had 3 buyers. Today it says “currently unavailable” on Amazon.com but I have stock (147 units) and everything thing looks good on the Seller App. I contacted Seller Partner Support and I’m waiting for a reply.

If it helps, yesterday I changed the charging method from one credit card to another, although I doubt this is the reason. I don’t think I violated any policy, I have been very cautious with everything I do.
