I've changed my eBay password, and can not get a new authorisation token, tried the procedure and it gets declined.
What am I doing wrong please?

Hello Mike,
Thank you for your question about your authorization. Is this issue still occurring? It looks like you were able to add snipes after you wrote, so it appears to be okay now. If not, please let us know so we can take the next step.
Please let us know if you have any other questions, or require other assistance. We are happy to help.
