Our team is now addressing any product data for all merchants using Search to ensure consistency across datasets. This process will be completed within the next few hours. Impact: * Only updated products were affected. * Missing data was limited primarily to SKU-level custom fields. * The total number of impacted products is relatively small, but we recognize that this may have caused undesired side effects in some cases. We appreciate your patience and understanding as we work to finalize data consistency across all merchants.
