Shawn -
I'll do a translation on that one.
In order to make sure that old data does not overwrite new data, QBO maintains an edit sequence called a SyncToken. If you make an edit in QBO for Bob Smith's invoice, it gets SyncToken 1. Then if Method edits it it gets SyncToken 2, and so forth. If another app tries to edit it with SyncToken 1, QBO says "no way, you have old data, we're not allowing it."
(that's the techie reason.........just in case you wanted to know!)
Now........why this happened to you....I don't know. It's the first time we've seen it. We ran a script that updated your tokens, so the invoices should be okay to pass through now. Please let us know if they do.
Are you using any other apps that might have changed these invoices? Did you modify them in QBO directly? Just trying to see if we can reproduce a scenario where this happens.
Thanks,
Paul
