Alex: You cannot find them in the notifications either. I see the roses for forum posts on my profile only. The roses for lessons are visible on the exchange page only, but they are hard to find because I cannot select for lesson roses only.
@all - I took a closer look into this, and the test account I used which seemed to have the same issue is actually working properly. I forgot that I had set up a filter through Gmail that automatically moved these emails to another folder.
We also took a closer look in the back end and at first glance things seem to be working properly. Would you check your spam folder, other folders in your email account, and your filters to make sure it isn't something there that would prevent these emails from coming to your inbox?
