macair keyboard keys fading
Keys on MacBook Air keyboard (Retina 13" - purchased Nov 2019) are fading, with the letters becoming invisible, despite careful use in rustproof environment. Apple has announced an extended 4-year warranty and settlement program for machines sold during 2015-19 due to keyboard issues. Local service providers recognise the fading keys, but say the warranty covers only 'non-responsive keys'. Has anyone faced this issue and found solution? Thanks.
