I'm getting 1-2 a day on level 10, but before New Year's, they were plentiful, and across browsers. I primarily watch them to make money and be able to afford the advanced stadium upgrades that come with level 8 and up. You'll spend entire seasons saving up the money for a $111MM upgrade without them.

It's very disappointing, especially considering that they did an app update that was supposed to keep them flowing.
