Hi there. Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers. It would be my pleasure to assist you with this. I always like to start with the simple things first. Have you tried shutting your MAC down and restarted? Alternatively, I could walk you through stopping all processes associated with the store app, but a simple restart will accomplish the same thing. Give this a try and let me know the results.
