Thank you! In addition:
After the issue did appear, could you please use help > send feedback dialog and send us the protocol by hitting the checkbox (“Send anonymous system profile”) – in the message field just write something to get the form sent.
Can you reproduce the issue after restarting the machine completely? (There’s a strange bug known by Apple not saving some properties e.g. in our case that the Tour is already done)
