When I click on copy app, i have the following error
An error occurred duplicating the app.
In most cases this is caused by a large and/or complex Google sheet. Delete all rows and columns that your app is not using or 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. Then try to duplicate the app again.
: Could not load the receiving user’s Google Sheets integration
Please, I need help

Have you deleted all rows and columns that are empty?

I had a similar problem in an app with many tables but only few with a lot of rows.
What I did:
First duplicated the Google sheet in Google drive
Then removed all rows (but left one) from the few tables which have a lot of data
Then copied the app and reconnected to the Google sheet duplicated in the first place.
Maybe this also helpful for you.

I have the same issue and tried to delete everything not necessary. Still it gives me an error.
I however used dummy data, as I don’t want people to use the real data, but overwrite it with theirs and localise the app for their group.

How many rows do you have in your project? Can you send us a link so we can try to see if we can copy it ourselves?
