Version/Build charts count users more than once

[joshuajung]

I noticed that „Versions“ and „Builds“ dashboard charts seem to count users more than once if they used more than one version or build on a given day.

As per the chart definition, I would expect each user to be counted for the last version/build they used on a given day.

How were you able to detect this? As this seems to be a big issue that would make my numbers look very different since I ship weekly updates.

I am using TelemetryDeck for a rather small TestFlight project and noticed that on days when I released a new version, I had about twice the number of users that were enrolled in the beta in total.

Thanks for reporting! Users are indeed counted for each version separately, and when we then stack the bars for each version, this gives visually the wrong information, i.e. it seems as if you're having twice as many users suddenly. We're solving this by removing the stacking in this view and displaying versions as a line chart from now on.
