Sharepoint newsfeed is emty for external guest users

DonnaSteinwand The web part doesn’t utilize search for fetching the news. If you check Fiddler while the web part loads, there’s no request to the search API that’d get the news. In fact, the web part makes a request to https://northeurope3-sphomep.svc.ms/api/v1/news/sites?start=0&count=13 to fetch the news, which doesn’t return anything for guests. This was also confirmed by the premier support: The issue that you see here on the news web part is not related to overall search but to a specific call that is made by the web part. It uses a call that does not work with guest users. The current behavior is by design. The required code changes to change the behavior are outside the scope of a fix and can only be considered for the long term. At the moment there is no timeframe when this behavior will change.
