Stona review for Mailchimp Email SMS Marketing

I thought my installation was done with Mailchimp since Mailchimp dissapeared from Shopify, but I just click on the ShopSync app and shows it is not connected. A message with "Temporary Installation Cookie Must Be Set Your browser is preventing the installation of ShopSync. A temporary cookie must be set by clicking here." comes up, but after clicking and refreshing nothing happens and the app still does not work. Please help UPDATE: The problem was solved and it was indeed related to the browser. Thank you!
