Yes. When I say just "yes", it always comes back with "Sorry, I don't understand what you said". But If I say "yes, please", it says "OK, I'll add that reminder". Very odd. But it understands the word "yes". Maybe it just likes the magic word?
When it doesn't understand my confirmation, it seems to lose the original item that it asked for confirmation about. This is very troubling. Then I have to start all over again.
