Thanks, just updated it now, and on my first newsletter on 3.6.9 it does not save the selection on different tabs automatically like before.
Do content, then save, then on 5Scheduling select time to start sending, when moving to 6 List, select the list and move to 7 Finish, shows an error that a list was not selected, and the Scheduling was also not selected. This means saving every tab’s contents before moving to the next one.
