What differences should I check in "Sync Comparison" on mobile, and how do I return to PI-0411 afterward?

1. Review the "Change Summary (Other Party's Version Compared with Our Current Content)" at the top to check added and deleted items, the expected shipping date, and changes in amounts. 2. Compare the "Our Side" and "Other Party" columns below to check the highlighted differences in the PO number, currency, trading terms, and other fields. Note that the other party's "Expected Shipping Date (ETD)" is 20260424. 3. Read the explanations at the bottom about version differences and the scope of application. 4. When finished, tap "Cancel" in the upper-left corner to close the sync comparison window and return to the PI-0411 details page.
