Use the same video, account, approximate time, and quality level on mobile and desktop. Note whether the phone is on cellular data while the computer uses Wi-Fi; otherwise a network difference may be mistaken for a platform bug. Describe exactly where playback stops and whether captions or audio continue.
Avoid private stream URLs and account details in public reports. Try a second title if safe to distinguish a single-file issue from a player issue. Check the provider’s official incident page for known partial failures. A mobile success is useful evidence, but it does not by itself identify the failing component.
