My FBA inventory is showing out of stock suddenly. I tried to reach customer support but I have doubts about the instructions they gave which is to delete the list and create again. I have no idea if that is going to solve the issue. I dont want to spend hours on a case where I am not responsible to begin with.

I sent my products to Amazon FBA warehouse before applying for a VAT registration. After some time the system prompted me to provide valid Tax number. Since my VAT registration application was still in progress I wasn't able to provide the Tax information in the given time frame. As a result first my listings became inactive then my account.

After providing the information and validation of it my account became active again. In the performance notifications I see that my FBA settings were restored (I also took the steps that were given in the notification)

Unfortunately no matter how many times I contacted Amazon support my listings are still shown as out of stock

when i trying to remove this stock , it is no choice for me to select quantity
