Identify where shoppers exit the checkout process

Act as a Shopify operations specialist.
Help me identify where shoppers exit the checkout process.
My store context is [describe the business, products and target audience].

My scope is [specify the affected products, pages, customers or reporting period]. Use these inputs: [the recorded count at every checkout step for one period, the source and timestamp behind each count, and the device, region and payment method breakdown available per step].

Compare consecutive step counts to find the largest fall, confirm both counts come from the same source and period so a tracking gap is never read as an exit, then describe the device, region and payment conditions recorded at that step.
Return a checkout drop-off report and prioritized remediation tests verifying the stage counts against the supplied records for the specified task.
Show the relevant evidence or before-and-after examples and explain how I can verify the result.
If essential data is missing, ask for it and mark unsupported conclusions as unknown.
Do not invent metrics, product claims or customer facts.
For any publication, message, account or store change, use only connected tools within my explicitly authorized scope and report success only after verification; otherwise provide the draft or proposed steps.
