Never got a glow notification. Last glow was apparently 4PM yesterday. I logged in around 2PM today, maybe earlier. Left to go shopping from 4 to almost 6. Logged in again around 6:30 or 7 and haven't left. (It's 11PM right now.)

I was told notifications were based on logging in every day, which I have been. (I just got the achievement for logging in 60 days straight just yesterday.)

I will note, however, that yesterday I fed my fish around noon or one, the usual time, but today I didn't remember to until around 10 PM. Could that have affected it?
