I have an mrec animated banner that has a unidentified rectangle in the top left corner. It is not an asset I have added to the stage.
I can't figure out how to get rid of it, without having to start again. I have turned off visibility to all assets and its still there.
Anyone have a similar issue?
Your browser will solve your issue. Browsers have a developer mode. You can open it using the browser menu. For example, using Microsoft IE or Microsoft Edge: Tools>F12.
Here is a screenshot with Google Chrome.
The selector tool is the rectangle with an arrow (on the left side). Here, the word error was selected.
