Authorize.net

The app doesn't work unless you delete your old authorized.net gateway. The app is conflicting with the old gateway and its blocking access. The app wouldn't bring up a spot for me to enter the API Login / Api Key. You have to fully delete authorized gate way from the payments section in your admin area and then install the app. I followed the email authorized sent me and i was able to enter the info and process payments again. Terrible app and the Shopify customer service is even worse. They should have checked this app was working before allowing it to be published. Especially for a tech company, this is downright embarrassing for them

Its been really confusing to keep receiving emails saying I need to update the connection, yet when I follow the prompts it just says that I am able to receive payments. After seeing so many similar reviews of this issue, I looked a little deeper and what I found was I went into Shopify payments, there was a warning saying that my connection to Authorize.net needed to be updated, When I pressed update, and it took me in to where I can select payment types.
At the very bottom I had the option to Activate, I didn't change any selections but did Activate.
Then everything turned green, and the warning is gone now, I am not sure if that is the case with others, but it seemed to solve my issue, but we will see if I receive another email saying I need to update the connection in a couple days.

This is a terrible update. As a subscription model, it has caused all of my members’ orders to remain pending. The transactions were successful, but no Shopify orders were created.
