While I was getting almost all 15 credit ads, since the new version came out, they're only about 50% of the ads I'm seeing, now, with the balance being 2-13 credit ads.
I'm seeing plenty of ads-- never more than a few swipes. (Android 6, v3.0). Depending on time, probably 50% are 1-5 silver. Just enough production that I probably wouldn't have immediately laid the phone down before the new lottery-- but I'm going to get those 20 entries even if they're only 1 silver each. I have a feeling that's part of the reason the lottery exists.
