Is anyone else having issues accessing the Concurrency Monitor in APM today? I'm receiving an error in all environments. An error occurred while loading this search. Please try again.

Yes, I have been having that error all morning - had it with the Health Dashboard and Record Pages Monitor earlier as well, but looks like I am no longer seeing errors there

Okay, glad to hear it's not just me. Thank you!

I've been having this on one sandbox for weeks now - upgraded to the latest (which didn't auto-upgrade for some reason) and still problems. For a while there it simple said the suiteapp is 'down' in a popup. Now it's back to search errors.
