I'm opening a case for this now, as well.  Does it seem like 4.18.2101.4 was pulled?  Seemed like it was released on 1/25/2021.  I seem to have a mix of clients on that version, and 4.18.2011.6.  Both claim to be 'completely up to date.'  Documentation seems to show that 2011.6 is the latest version.......

 

Any traction on your case?

I've experienced the same issues and come across this thread. 4.18.2101.4 was definitely pulled as MECM shows it as expired and superseded on 1/30.

 

4.18.2101.8 was released today and from my limited testing so far it appears to resolve the issue.

    adamgrieger we have seen issues with 4.18.2101.4 and .8  it looks like there is something still going on. Hopefully, your testing goes well but I would continue to test at this point.
