Hey, [email removed]Mimi17! Welcome to Shopify Community!
I’d love to help you out and resolve the issue that’s preventing you from closing your store. Could you please share more details about the issue you’re experiencing so I have a better understanding of it? If you have screenshots that show the absence of the Settings button, it would help me quickly find a solution.
Feel free to share any relevant information here and I’ll find a fix then. Thanks!
