The issue is happening because we assume that in case of warm and hot launch, we would have the last visible time recorded. However, for certain OS version it doesn't seem to get set. A quick fix for this is implemented: https://github.com/measure-sh/measure/pull/1183.

Keeping this issue open to address the root cause. We'll need to investigate for which OS versions or devices this is happening as we'll be unable to report hot and warm launch time in such cases.
