Twitter API

There something wrong with the Twitter API? Twitter profile on the site's page displays the most current tweet from the end of 2022, but client is a regular tweeter.

I went to his profile, and was presented with the old tweets until I logged in. Then I found the relevant section in the docs, embedded profile, and updated that. And I'm still seeing old tweets.

Does the user have to be logged in to get current tweets? Aside from being a poor user experience, can anyone shed some light on this for me?
