Issues after Domain Change

I just recently changed our district website to a new domain and have a couple of issues. On the meeting page, the links to individual meetings still have the old domain address. I’m not seeing a clear way to edit them. The individual pages did change automatically. It’s just the list has the wrong links. Also, how do I get my new domain linked with the app? Thanks.
