Using my Xero trial account with accepted invitation into our company Xero account I created Xero OAuth 2.0 app. Then I need the authorization code to be able to get tokens and have access to Xero API. I sent the Auth URL to my colleague who has permissions to grant me access to our company data so she can pass me the authorization code but the Auth URL isn’t working for her. Everything is set up correctly according to Xero YouTube videos and documentation. The URL works because when I access it, it prompts me to log in and gives me selection for an organization. But I don’t have permission to select our organization which is greyed out. My colleague is supposed to grant access to me but the link is not working for her. Please give me hint what are most common reasons for this issue. Any help is highly appreciated as we need to hurry with our internal reporting and we have lack of data when we can’t access them.

We tried different browsers, I tried to adjust scopes, my colleague invited me into our organization but nothing worked to resolve the issue.
