Based on the plan you are subscribed to, you will have automatic access to the session profiler. With each incoming report, we collect a plethora of data over the course of the application's usage. from its initiation up until a report is sent. The data is then displayed in the session profiler for each bug report as a timeline.
One of the pieces of information we capture is network connectivity. This will display the user's network, internet connectivity type, and any changes over the 60 seconds prior to the report being sent.
For more information regarding the session profiler, please read more in the docs. The session profiler is enabled by default.
