The new update messes up the personal heatmap in a few ways:
1) All of the color options are now much lower contrast than before, making it harder to see the cumulative and specific activities.
2) The color intensity calculation is wacky. Routes that have only been run once will vary in color intensity, even within a single block.
3) The map really lags in updating now. For instance I uploaded an activity more than 8 hours ago, which shows in the feed, but still doesn't in my heatmap. Before this update, it would show up within 5 minutes or so at all scales. I'm worried it will start dropping activities entirely.
All of these create clear degradation on the #1 feature I subscribe for. Please fix.
These issues show up on the Android app & web browser (Chrome).
