Amare Post Op Shop review for Linkpop

This app has not been w2orking for weeks. Shopify support has kept me on the chat for 3 hrs at a time, 3 different times and it is still not working. the link that link pop generates is not secure and no one can seem to fix it. this app is useless. Shopify support has told me to reinstall and uninstall, use a different device and browser and etc, and STILL no one has been willing to help me or tell me what it keeps giving a server error. This is a problem with Linkpop directly and they refuse to fix it. This app is useless. It has been weeks and no one will help and the link does not work. Useless.
