Paid extension. Not a problem with that. The developer misled me from a screen pop-up related to bookmark checker, doesn't mention this in the Chrome Web Store, and finally, not when you first access the extension. Only after signing in does the user find out it's a paid extension. Save your apologies...just bad marketing. Wasted my time! Scam!
