I decided to go through the U.S.A. SSPX chapel directory. Specifically, it was to see if any of the chapels refer to the local (diocesan) bishop. If the chapel had its own website, I linked to that. Here are the results. Please note that, while I provide a link to one specific section of a website or bulletin, I did skim through multiple pages. If I missed something, please let me know.
Lastly, although not my priority, I did not see links to social media (Facebook, Instagram, YouTube, Twitter), except for the official SSPX media, if there was a YouTube channel for online Mass streams, sermons, or catechism classes. If I did notice one, it is referenced.
Conclusion: The North Carolina Mount Holly Chapel is the anomaly regarding the reference to the local diocesan bishop.
