Disable "Explore App Designer" banner in GUIDE of MATLAB R2019a

Since I updated MATLAB to version R2019a, this banner will permanently show at the bottom GUIDE window.

There's no close button for this banner, and with it I can't resize GUI or reach objects underneath it.

Is there a way to remove this banner?

Please, someone from MathWorks needs to address this. This can't possibly be a permanent banner.

How do you get rid of it in 2021? Option no longer in Preferences.

I had the same problem. However I found a solution: go to File > Preferences and uncheck 'Show appdesigner message panel'. This will remove the banner and you can resize your GUI again. Would suggest to MATLAB to just place a cross there which closes it.

Thank you Rik Bokhorst. It works.
