Error duplicating app

I have encountered a problem with the application duplication. It says that there is a large amount of data in Google Sheets. Although the tables are not associated with the application

Error text: An error occurred while duplicating your app
Duplicating an app can fail when it uses a large or complex Google Sheet. Please delete all rows and columns that your app is not using or where there is no data. Glide will append rows as needed, so you can remove all empty rows below the existing data on all of your sheets. After completing these steps, try duplicating your app again.

Error duplicating app
Error: 1003

What do you mean by this? Do you mean you have many tables in Google Sheets, but you don’t use all of them in your app?

When you connect a Google Sheets spreadsheet to Glide, unused sheets are still connected to the app.

Sorry, my mistake.

All my google sheets are used in App.

Thank you.

So do you have a lot of sheets in your file? How many rows are we talking about here?
