UPDATE: it seems to work now but 3 weeks have gone since my certification..
As you can see I have the Google Advertising Professional certification, see the logo on the right.
But a real problem is that the link
(https://adwords.google.com/select/ProfessionalStatus?id=2A8NuRDuoVNOF560mTwGcw&hl=en) that leads to my page does not work at all, it asks to log into Adwords.
How many readers or potential customers lost?
Google just answered me that for some professionals there is a bug.
Is Google going to give me a compensation for potential loss?
Actually a french company already ask me if I were really certified as they are unable to display the page.. 🙁
