Project Description: I need help fixing an error in my Google AppSheet app. Error Message: “Unable to fetch app definition. Error: There is a mismatch in the number of columns between the spreadsheet for Customer data and the table schema. The table has 11 columns but the schema has 9 columns. Please regenerate the table column structure. Error: Data table ‘Customer data’ is not available. The data for this view cannot be found. Please select a new data table in the view settings.” ⸻ Requirement: Looking for an experienced AppSheet developer to fix the schema mismatch, reconnect the table, and make the app work properly.
