Send notification email not working
The "Send notification email" checkbox is defaulted to true when using salesforce classic for case ownership change, but not in lightning. The "Notify Case Owners when Case Ownership Changes" setting is set to true in Case Support Setting. Does anyone know why is it not working in lightning?
Please refere the following idea (https://success.salesforce.com/ideaView?id=08730000000ZXIdAAO) and this post (https://success.salesforce.com/answers?id=90630000000Zcl9AAC)
