Reconcile Wizard workflow question

I have a question about the Reconcile Wizard workflow from Tiller Money Labs. I have a lot of manual transactions, so I first tested it on a subset and it worked great.

I then updated all my manual transactions to have the right metadata and transaction ID, and now the “Reconcile Wizard” is stuck on “Searching for unreconciled transactions in your Transactions sheet”. Seems like it has timed out.

Is there a limit on how many manual unreconciled transactions I can have at once?

I removed the Metadata for the manual transactions after the end of July and it worked, so it must have been too many transactions. I’m interested in knowing what the max is.
