I have a Xbox Elite Series Wireless Controller 2, my "A" button sticks when i press it

Hello everyone, i had purchased a Xbox Series Wireless Controller 2. It is still under warranty till 12/12/2023. Lately i have been facing an issues specifically with "A" button. Whenever i press the button it tends to stick and then pops out on its own. Can anyone please help me with a solution or if i can give this controller for service.

I only use the controller for specific games and i do not use it too much but not too rarely as well.

Any solution is helpful.

Thank you.

:)
