It's no longer M.P.A.A. - Since 2019, it's just M.P.A.

The organization previously known as "Motion Picture Association of America" changed its name officialy in September 2019 to "Motion Picture Association," eliminating the "of America" part.

This change is explained in the official website of the M.P.A. thus:

"2019: Chairman and CEO Charles Rivkin unifies the global operations of the association under one brand: the Motion Picture Association (MPA).

Since then, November 2019, the change is observable at the very end of the ending credits of many of the movies rated by this entity. If you stay until the very end of the movie, as any true cinephile should do, you will see the certificate number issued to the movie and the iconic MPA "globe and reel" logo crowned by the acronym MPA:

Now, what does all this have to do with IMDb?

Official ratings are one among many kind of data that IMDb compiles and displays on each movie's page.

Every Tuesday, the MPA releases a weekly bulletin with the latest ratings of new and upcoming movies:

These new ratings are immediately incorporated into IMDb by contributors, so yesterday for instance the musical remake of "Mean Girls," just to mention a prominent new movie, was updated with its MPA rating added to the pertinent section of its IMDb page:

https://www.imdb.com/title/tt11762114/parentalguide

However, as you can see, the organization is erroneously credited by its former name MPAA and not by its current name MPA.

The change from MPAA to MPA has yet to be applied to IMDb, and we are 5 years into the MPA era.

Therefore, I strongly suggest that it's high time for IMDb to start using the proper official name MPA, and furthermore, to start retroactively correcting all the MPA ratings of movies rated and released since November 2019 (when the change took effect on movies' endcrawls), from the erroneous MPAA to the correct official name MPA.
