❗❗❗❗❗ @FixeyPlatforms I ALREADY EXPLAINED WHAT YOU NEED TO DO IN MY COMMENT ON YOUR FIRST ISSUE. STOP WASTING TIME SUBMITTING POINTLESS DUPLICATE ISSUES AND FOLLOW THE INSTRUCTIONS FOR THE CORRECT SUBMISSION PROCEDURE!!!

@FixeyPlatforms please don't submit pointless issues to this repository. The Arduino Library Manager Registry contains thousands of libraries from hundreds of authors. Finite resources are available to maintain this resource which is so important to the Arduino community. Pointless issues waste those resources and so this is irresponsible behavior.

⚠ Repeated irresponsible behavior may result in the revocation of your Library Manager Registry privileges.

Thanks in advance for your cooperation.
