Database not uploading

I followed this tutorial (https://docs.thunkable.com/thunkable-cross-platform/create/components/data/spreadsheet#getting-uploading-updating-and-deleting-data-in-a-spreadsheet) and it says I have uploaded my data but when I go onto the spreadsheet it is not there. Any ideas on what the problem might be?
Thanks in advance

First, you need to check if there is any connection to AirTable at all. To do this, you need to write down the data in AirTable and try to get them in the application. If this works, then add the data to the table and see if any errors have occurred.

If you give me a link to your project, I’ll be able to see the cause of your problem faster.
