Recent issue between Twitter & links to LinkedIn posts/pages when on iPhone / iOS

There seems to be a recent issue between Twitter & links to LinkedIn posts/pages when using iPhone/iOS/Safari. Older links from 3 wks+ ago still work OK but more recent links to LinkedIn from iPhone device get directed to a LinkedIn 'page not found'. All these links work OK when on laptop. Have tested various types of links. Issue is experienced by others on iPhones too. See tweet here - the older link from 3 weeks ago at the bottom works OK on iPhone, others don't. Can anyone help please? bit.ly/3I7fVWm
