I experience an issue where an user is not being able to add or modify any workflow but few days before was able to do those actions in a daily basis. From the user view, it looks like this, mentioning that the campaign is in "read only" mode and has the activity options disable.
Can't access those options and not being able to modify the workflow.
What is causing the issue and how to fix that for this user ? Where is the options to solve the problem ?
