Highlighted Content (Webpart) has stopped updating

[DMDrew]

I use the highlighted content webpart to pull the most updated documents from multiple SharePoints into one page. However, today it's not updating. Even when I click "see all" it simply shows a snapshot of yesterday and doesn't list the newest files. Yesterday during a troubleshooting session I had my team's SharePoint "reindex" itself, would that effect this webpart in this way? If so what is the solution?

It is dependent on search. If you did a reindex, it might take some time for it to process the request. I would recommend giving it some time and check.

Is there a way to speed the indexing process up? I did the reindex last Friday and while the webparts have updated since then, they are still behind as of this morning as they show a snapshot from yesterday not this morning.

Unfortunately no. We cannot control when the indexing job runs. As per MS it should run once every one week. Note: My answer is under assumption that we were talking about SharePoint Online not on-prem.
