The pandemic hasn't stopped Google from releasing app updates. They have historically had a freeze period during holidays, but you can go through the version history on the iOS app store and see that they manage to update their apps several times per month during other periods of the pandemic during 2020.
I don’t buy it for a second. Facebook updated, and one of them, (I think it was Messenger), they just went through and checked every single box, because they know as well as Google that most people just don’t care.
