We recently updated our URL from the native shopify URL to a dedicated URL. This caused a hiccup in the connection which has been fixed. but we have not changed anything in the code (i.e. the code above used to work correctly and now does not).
The issue is that clicking that link is supposed to open an overlay window with a product review form, which it does, but since fixing the connection from the review software, clicking the link ALSO opens a new blank tab "about:blank#blocked" as the active window. How do I stop the blank window from happening?
