Bests & Worsts Reviews from Amazon

we have used this for 6 months for our baby. out of the blue the other day, we woke up go a crying baby and no white noise. put the baby back to sleep, went to turn on white noise and very loudly comes on asking to upgrade our service. wakes baby up again. last night it stops, go to turn it on and for 15 seconds its talking about leaving a “5-star review”. I think its ridiculous to suddenly start charging or changing the service. now it turns off every 4 hrs. update: baby woke up, white noise was off, tried to get it to restart and it went into a spiel and wouldnt turn on. desperately searched for a new app and baby woke up permanent for the night at 3 am. thanks. deleted the skill asap
