How to understand the result
The browser sees OS events. Macros, speed dialing, and loss of focus can affect the results.
Compare multiple runs under the same conditions. Then change one factor: connection, device, or setting. If the symptom persists, repeat the test on another device and save the conditions - this will help to more accurately describe the problem to support.
