Did something happen on August 2, 2021 to cause missing historical data?
Some stocks are showing no historical trading data on August 2, 2021. One example is CRBP. I was going to post a picture of this...it just shows historical data for CRBP (Corbus) with a blank row for August 2, 2021, and I believe the stock traded actively on that day.

OK, so I just chose another stock (AKBA), then tried CRBP again. This time, there is valid data for August 2, 2021. So, this is not a consistent error in the data, but maybe an issue with data versions?
I believe this is happening with many other tickers as well.
