Why are some charts such as “OS Distribution” for example showing more devices than the total number of installed app?
The distributions are not snapshots, they are counts of devices that match the metric displayed within the time-range. For example in “OS Distributions” if users upgrade massively from one version to the next within the represented time-range, they will be counted in both versions.
What is the maximum number of event properties that I can define per event? What happens if I send more than the limit?

There is no limit on the number of property values that you can send. However, you will see the five values with highest count.
What is the maximum number of distinct events that can be sent per app?
You will be able to send 200 events with distinct names. However, there is no limit on the maximum number of events instances sent per device.
