24s need this update, until then nothing you can do or enable on your phone to make it work. Its still in early access though, so hopefully it goes out to everyone else soon.

This update will enable the other piece for Android Auto battery estimation on the 24s, I just got this a few days back and it started working for me finally. https://www.f150lightningforum.com/forum/threads/sync-25-2-1-6-5-walk-away-lock-clean-up-eap.27717/
This is not working on my 24 Flash also, even after 10.1.1 so I think they have not pushed some part of the software udpate that enables this feature in Android Auto yet. Even though it says it requires 10.1.0 in their own help documenation... its quite confusing and frustrating.
Typically in software updates things are cumulative, particularly with minor and patch releases like this so I would expect it to contain everything in 10.1.0 also.
Wondering if there is some feature flags that get turned on separately like they saw for karaoke that will turn these things on...
My 24 Flash just got 10.1.1 today and I'm not seeing this either in my truck on Android Auto. I have everything up to date on my phone, will also play around with it and see if I can get it to work.
