Hi - I have 35 JavaScript buttons that are not working in Lightning. I went to the Lightning Experience Configuration Converter and followed all the steps to convert them. Unfortunately, none of them are working in Lightning.
The Reason for all of them is "Mass action buttons aren't supported" and the User Impact is "Can't be calculated for this button type"
The similarity all these buttons share is that they pre-populate some fields upon clicking them (Primary Contact, Date, Deal of Interest, etc.)
In classic, all of these buttons work just fine. In Lightning, the buttons still appear on the page layout, but when you click on any of them, the fields do not pre-populate anything.
If someone has any idea on what I'm doing wrong, that would be great. Thanks!
Also, at this moment I don't have information to confirm if it is planned to increase conversion support in near future releases, but there are multiple development teams working to help the transition to Lightning to be easier
