Hi, I recently upgraded my umbraco site from 8.15.1 to 8.18.11, because I need to comply with a security update.

And then I all of a sudden had a lot of issues with my redirects. Both skybrud and url redirect management ones.

I resolved some of the issues, but others persist. And I have not realized why.

I have this line of code:

var redirectRule = _redirectUrlService.GetMostRecentRedirectUrl(requestRoute, publishedRequest.Culture.Name);

Where "requestRoute" is something like this ""3631/path/to/item". So {id}/{path}.

When the site is not upgraded yet, a redirect is returned from the method. But when it is upgraded, this method returns null, without much else info.

Does anyone know why this may be?
