We started using Trello within my company, and we love it. But there is one thing that could be a total deal breaker: email notifications are not working as expected. According to this post, we should receive notifications via email when added to a card, invited to something or a card we were assigned to changed. None of these happens to us. Yes, we did turned on email notifications, I even have it set up to send them immediately.
Also, when I first started using it on Google Chrome, it asked me if I wanted to allow Trello show notifications, which I did. Never seen a chrome notification popping up either.
Are we missing something?
