Another Reversed Google Update / Bug ?

Looks like something is brewing at Google. Apparently, there was another update and looks like some of the SERP position tackers are noticing a big change as well. In SEMRush I can see a 9.4/10 on 16th volatility score in the US and a 9.4/10 volatility score in AU. Some users also noticed that most of that change was short-lived and has been reversed, similar to what happened a few days ago that was confirmed by Google as an indexing bug.
