Google Search Algorithm Update Fluctuations - March 20th to 22nd

As you know, Google confirmed a core update on Feb 22, 2019 & March 12th. Around March 20th, 21st and 22nd, the SEO's on the forum chatter spike back up a bit.

However, this is update is unconfirmed - March 20th through 22nd. It might be related to the March 12th roll out that can take weeks to fully roll out according to Google:

Here is some of the chatter from WebmasterWorld around these dates:

My traffic seems to be down to a trickle today after a huge recovery last week. Whatever they did today has reversed some of the gains. I think it's better to not get too excited anymore :/

We were not hit by any significant penalty in the past, and we got a decent boost with the initial update.Something changed yesterday, and we are now below the pre-update level.

My homepage is showing some signs of life today. It’s sometimes popping up on page 2. No traffic increase. Desperately praying for a turnaround at this stage.

They are definitely tweaking something today. Feels like the core update.

Then, March 12, boom, I was almost back to where I was last year. Traffic climbed until March 18, then started dropping again and I've lost most of my gains. I'm not sure what's going on.

Here is what the SEMRUSH tool show:

Have you noticed any change from the March 12th to the March 20, 21, 22 timeframe?
