DOES AXY VALIDATOR WORK WITH CLASSIC ?
Yes. Axy Validator works with both Salesforce Classic and Lightning
If you work on Classic UI, access Axy Validator app going to the App Menu in the upper left corner of your screen.
Then click on Axy Validator and you will be shown the Axy Validator Setup page. At this point, the operative for defining rules is the same. Go to CONFIGURATION/How can I configure a rule?
