I just got a warning that my version of Deployment Manager can be upgraded.
So I upgraded to newest version, and it installed successfully.
So I went to upgrade my environments and it did not say it can be upgraded, tried refreshing page, leaving back and coming back. It still didn't ask to upgrade the environment.
However, after doing a health check did it ask to upgrade, not sure if this is because it doesn't know the version on the environments until you do a health check.
