standard print widget on web app builder not working when legend ticked on

[KateO_Loan1]

Has anyone had an issue with web app builder where the print will fail if the user ticks the option for display legend?

First time i get an error, unable to get property 'renderer' of undefined or null reference

next time nothing happens....

Any suggestions?

I am also facing this same issue with the default web app printing widget. We are using 10.6.1 ArcEnterprise

Has there been any solutions or workaround to this issue? 

Kind regards,
