I could have sworn I created a discussion about this already, but can't find it.
I have a Seller account for my small business and overall it has been working fine. However, a few days ago, we got the dreaded "Invalid charge Method" message and the Android Seller app goes into a loop it can't get out of.
Logging into web, I see the Invalid Charge Method message in the UK marketplace. I can change the card to another card, it takes the validation payments from it, but the message doesn't go away for either card either. Both cards have been used in the past.
I was initially informed by seller support it would be billing address, claiming the bank is rejecting it, but that's not the case. The bank confirms it isn't the case, as the validation transactions were taken from the card. This card has worked for the whole time (over a year) that I have had the pro account. So it is strange it doesn't work now and stopped suddenly.
We are active in 12 marketplaces overall. All the EU, the UK, USA, Mexico, Saudi Arabia and the UAE. The USA is working fine. All others are not.
At one point in the past, one of the cards didn't have money in it and I recall at that point, it came up with invalid charge method. So I used a different card, the current default and it worked. This time, there is money in the account and it's basically just stopped. Amazon seller support have not been very useful. They just created a ticket and have just shelved it from what I can see.
What makes it worse, is I'm still getting orders via our FBM. But I cannot log in to get the address to send it to because of this, and it needs to go tomorrow.
