streaming show episodes won

The website for a weekly music streaming service won't update to show recent episodes. However, I can access these episodes from the same site on my MacBook. I've tried refreshing the page on the phone, turning the phone off, accessing the site from a bookmark or by typing the name in a search engine, but it still won't update. I normally listen to this show on an older phone, but I'm away from home and using my primary, newer phone through a hotel wifi network. This phone was updated just a few days ago to iOS 18.3.2. Could that have affected anything? My podcasts seem current, and a different weekly music streaming program seems current as well. Is this some quirk with the streaming service, or with the phone?
