Please do send over credentials to the staging site that was experiencing that conflict between Yoast SEO and APM, since I wasn’t able to replicate the issue on my own localhost (that conflict has been reported elsewhere on our own forums, too). Of course, we always recommend restorable database and file backups before providing us access.
Secondly, please do explain how/why the “/events” slug isn’t part of your URLs.
Finally, would you be able to share an annotated screenshot, screen capture video (and the relevant URLs for each) to clarify exactly what’s happening here?
