What should I check if checkout reports a payment problem?
Do not follow an unrelated payment request merely because checkout reported an error. If the seller confirms that no order exists, ask what step is appropriate before trying again.
What should I do if checkout changes my selected option unexpectedly?
Check order records if you already pressed the confirmation control. Contact the seller using the existing reference if an incorrect order resulted.
Where should I look for guidance on using the product correctly?
Distinguish official product guidance from an individual's suggested use. Check whether guidance applies to your intended context of use.
