Wont let me up up my Ai companion?

Can someone who knows or can help me out of finding out why my Ai companion say "Extensions are not currently supported by iOS devices." i try resetting it nd everything nd see if there was any errors.

Apple's policies do not allow us to load executable code not previously reviewed by the App Store team. Therefore, extensions in App Inventor are not supported on iOS, hence the error. You will need to remove any extensions from your project under the Extensions category.
