Cursor-down not working 100% on a end-of-2019 MacBook Pro I've been using a MacBook Pro (ordered in Q4/2019) for about 6-7 months now, and one of the keys (cursor-down) is often reacting sluggishly - I have to press it much with much mor force  than normal. The key shares the cursor-up function, and that side is totally trouble free.
Is there a safe way to release the key cap to check if it's just a matter of cleaning a speck of dust that may have gone down there? I have found videos that show how to remove a regular key, but don't want to risk destroying the presumably tiny plastic piece on the double-function key...
Also, is this keyboard known for being problematic in this way?
This sounds like a typical symptom of the butterfly keyboard.

your Mac is less than a year old and should be covered under nornal warranty.
It may be covered under the Keyboard Service Program

Both the 13” and 15” MacBook Pro laptops are covered under the program.  I wouldn’t  attempt a fix as any damage may nullify your coverage.  Just take it in.
