I have a workflow where a new Smartsheet row creates a Xero sales invoice and until a week ago it was triggering consistently for every new row in the target sheet. Now it has stopped for no apparent reason, with no Zap edits made and no changes on the Smartsheet side either. New rows have been added Monday, Tuesday, Wednesday and Friday this week and none of them has triggered any response from the Zapier side. The last run in the history was on May 10th.
Is there any reason why a trigger step would simply stop working like this?
