Google Discover sites disappering

There are a few documented cases of sites that were doing perfectly fine in Google Discover completely vanishing fro the feed recently.
For some it started after the 10 August "glitch" and never returned. Others say it started last week sometime before the sensors started spiking.

Anyone here have the issues?

Yes, i have the same issue and found the reason at this link

That update was not confirmed, though. How are your rankings otherwise?
Most sites this happened to (both 10 Aug and later on) say their rankings are stable or even improving.
