Hello, Mariano.
ProAdvisor Academy is currently offered in the US, Puerto Rico, the UK, Australia, and Canada.
To successfully log in, you must be signed in to QuickBooks Online Accountant (QBOA) to access the ProAdvisor Academy. Logging in with a regular QuickBooks Online company account will not work.
Just a heads up, the international customers can still get certification and training as long as they are using QBOA.
Let us know if you have further questions, and we'll be right here to help you anytime.
