How to acknowledge warning?

[Bjanders]

I got the following warning earlier, and now every time I start Fusion 360 I have this notification, with no design open. I have read the warning. How do I now acknowledge it, and make it disappear so it isn't there every time I start Fusion 360?

To answer myself: Just press the X that appears in the top right corner of the notification, like you always have. For some reason I didn't notice this now.

The usability issue is that the X appears only when you move the cursor close enough to that location. How is the user supposed to know that an X magically appears when you move the cursor close to where it will appear? I suggest that the UI is improved by always clearly showing the X. (In my case below, the X was slightly obscured by the message, even when I finally got it to appear.)
