Troubleshooting Reconcile Transactions

Hello. I hope you are well and in good spirits.

I have two Tiller Google sheets, one for last year and one for 2024. The Reconcile Transactions extension works quite well in the 2024 sheet, but in the 2023 sheet it stalls immediately upon activation.

How do you recommend I proceed to troubleshoot this?

Thank you.

Are there any major differences in the column headers between these two spreadsheets in the Transactions sheet? If there are any errors (ex. broken data validation) addressing that might help.

Otherwise it might just be a large data set crashing the tool.
