i followed the steps here to add in Email Action for Salesforce1 user to send email from their tablet/smart phones. I have added the Send Email action to all my case page layout but in my Salesforce1 i do not see this action on the case.
If i login from mobile website to Salesforce then I am able to see the Send Email Action. Why is that?
Ok, solved. I had to uninstall the Salesforce1 mobile apps and re-install again and the Send Email Action appeared.
