Error re-installing the app - How to solve
Sometimes when a merchant is trying to re-install the app he just can't because the app shows an error.
This is a common error and it happens due to Shopify Cookies, basically when you re-install an app you yet have cookies from the old installation, and this is why the error happens, because it conflicts with new/old Cookies.
Fortunately, this is an easy-to-solve issue, just clear your browser Cookies OR open an incognito/private window and install the app there(in this window/tab), it will successfully install after that.
