This is the version I use : SugarCRM Enterprise, Version 188.8.131.52 (Build 151) (Winter '18)
And I have Customer Journey 4.6.0
In Accounts or Contacts, even if I create a new entry, I can not create a new Journey because the + sign doesn't show up. I can click on the subpanel bar to open and close the module but that's it.
Would uninstalling the module and reupload it do the trick ?
