I have several entities in my sandbox environment that I enabled attachments for. I then added the timeline component to the main forms and it all works as it should. I export the custom solution as managed and import it into my production environment. The forms still have the timeline which generates the following message: No records can be displayed since this entity is not enabled for Notes, Activities or Posts. And sure enough, the entities that are enabled in the Sandbox are not enabled in production and as production is a managed solution, I cannot make that change. Does anyone have a solution/suggestion for this?
