I’m confused.
There is this, from a few weeks ago:

and there is this, from the end of April:
and according to this guide
SoM should be in the AQ phase
but when I look at my Battle.net client I can’t find a current Season of Mastery category, or either of those realms. I do see a category for “Classic Season of Mastery PTR” but nothing for live.
Does Season of Mastery exist only on a “PTR” server? I never even looked at SoM.
This video is a reasonably recent discussion of the state of Classic Era servers now
I hope someone else is more dialled-in.
