I would like to set a table field in Glide Users table to a value when the app finish loading. For example, when user A login into the app, I would like to set user A table field(location_selected) in Glide Users table to a null value when the app finish loading.
You might want to try an AI component (this one is perfect for your use case!), but switch the action to a set column values for User Profile > User profile row.
