I have a workflow that trigger when firstname, lastname, email and phone is change on contact forms. This workflow works perfect, but recently we discovered that this workflow was triggered EVERY TIME a form submission was done (matching rule relate submission to existing contact - therefore NO new or NO change on trigger fields).
In log I see that for every FORM submission SYSTEM sends and update to the field /timestamp of form submission/, at the same time my workflow trigger.
I have reasons to believe that this happend after a recent update from Microsoft.
Any suggestion to how I can work around this?
