Kind of infuriating because the same thing happened to me, but all of the apple stores were closed in CA so I had to go to Unitek to replace the battery for $$$ and it took them 21 days. Really not cool of apple not to say anything about this to their customers.
Now with Big Sur 11.2.1, my MacBook pro won't charge at all, even though my battery health is fine. Going to try and downgrade to Catalina right now.
