Unable to connect to the exisitng Google spreadsheet with my form

I had an unlink the
data input from my old Google sheets and connected it to a new for google
sheet as I was instructed.
Unfortunately it is not allowing me to reconnect it to the old form now.
Is there any way I can get the updates to happen on the old Google sheet
account where the information used to be stored as I have tabs on the old
Google sheets that are necessary for me to stay organised

When we integrate Google spreadsheet with a JotForm, it automatically creates a new spreadsheet in the Google Drive. You may try reverting the form to an earlier working version from the form revision history. Please refer to the guide below that can help you with Form revision history to restore the form that is connecting to the earlier version.

However, the submissions received during the connection with new spreadsheet may not be updated in the old sheet. Otherwise, you may need to create the tabs in the newly integrated spreadsheet. We are sorry for the inconvenience this may have caused.

Please check and let us know if you need any further assistance. We will be happy to assist.
