On Jan. 23rd I received this reply from AppleCare Support:
Engineering is still investigating the issue you are experiencing with not being able to see the Keyboard Battery level in system preferences and I will reach out to you with any updates they may have.
It's been two weeks since I contacted them about this issue.
Typical for Apple - you pay good money for an AppleCare Plan expecting prompt service, then they take weeks to respond.
Several times I've never heard from Engineering after submitting an issue, and was never able to get additional email replies from the reps either - the issues were just ignored/forgotten.
Today I received an email from another rep about a different issue.
After talking to her on the phone and sending several screenshots in multiple emails, she now says:
we do not troubleshoot through email, as apple policy doesn’t allow for it at this point in time...Im sorry but you will have to call the mainline if you would like more done at this time.
On 12/31/15 she said:
I’m going to send this one to the engineers to have a look at it and see if we can get a final fix.
On 1/13/16 she said:
i got the response from them last night just before i was leaving for the night.
But they are investigating the issues with the podcast setting not working as intended
Again with the "engineers," and a month later I still haven't received a solution.
I think engineers is Applespeak for TRASH CAN!
It should be called an AppleDoesn'tCare Plan! 😠
So it seems likely that the "engineers" aren't looking into this keyboard power level issue at all - we're on our own.
