Missing from client's development team

Hi there, I'm added to my company's development team and face no issues creating/deploying apps there. However, a client has tried to add me to their team. I can clearly see I have admin permissions in app store connect, however when trying to create identifiers for the app, it redirects me to developer.apple.com where I do not seem to have access to the team. I can see my company's team in the top right, and no option to select the client's team. I also cannot sign the app, as it appears I'm not added. The client has an organization account and appears to be setup the same way as my company's, so I'm at loss for what the issue is.
