If you export the field using the export-fixtures command, any changes made to the field will require you to reapply the command “bench export-fixtures” to update the custom field. However, with every site update or migration, the field will also be updated automatically each time.
I’m using Frappe version 14. I followed your instructions for exporting data using bench export-fixtures and enabled ‘Sync on Migrate,’ but the changes still aren’t showing up.
