I can't get assist meetings to work either. The assist sleep function works very well - I can even turn off my phone and turn it back ok - it still wakes up in the morning and turns the volume on. The driving assist works great as well - had it announce text messages and send the automatic reply.
The meeting function - not so much. I don't use the on device calendar - all of my appointments are on a corporate exchange calendar. Even when I have other people invited to the meeting it isn't working. When someone calls me that isn't a favorite it rings like normal...
Ideas? Anyone else having this issue?
