Include the details that change the answer
State the country if relevant, device model, app version and interface language. Add the order reference and exact error text. If you translate the message yourself, include the original wording too where practical.
Keep the evidence focused
Crop a screenshot to the relevant screen and hide personal fields. List the checks already tried in the same conversation. Do not send passwords, one-time codes or payment-card data; those are not troubleshooting details.
An illustrative comparison report
Template, not a customer case: Country [if relevant]; device/player [versions]; interface language [language]; original error [text]; A [conditions and result]; B [one changed condition and result]; order [reference in private support]. Hide credentials and personal fields in any screenshot; no full address is needed.
