Hi
Have seen it impact many sites. Most down, a few up. It is the continuation of the roll out or tweaking of the medic update. So the first major update August 18, then March 19 and then the June one referenced.
It was poorly named as the medic update - it really should be called the "entity update" or the "trump update". Most are saying it is about content - it is far more complicated than that. We have recovered a few sites from the August update. If your business sits within "YMYL" verticals - then there is plenty to be done. Usually, the largest job however in time, is a content audit, and then a re-write as the content usually coming up short on audit. The technical elements are just as critical from schema markup to uniform citations etc.
Not sure it helps, but your not alone.
