Key Product Options, Variants

Was not as easy to install as the Migration Guide indicated. Several steps were not as described, and then I found out I had a Shopify 1.0 Theme. I tried following the instructions for Legacy themes. Installing the Keystone code was ok, but there were no instructions about removing the SC Product Options code, which I had been using. I basically had to give up on my old Theme that I really liked and had a great deal of personalization on and switch to a new Shopify 2.0 Theme, so that I could add the "app block" into the theme. So, it took over 2 hours instead of 10 minutes and I am still not done. I have the core of my store up and running (I hope), but have a lot of fine tuning left to do.

Their support team did reach out to me afterwards and offered to help with removing the old code. I had already switched over to the new theme and had decided to keep it since it was a more up to date theme and easier to use. However, another issue came up with certain payment options not functioning well with the app and they offered to help get that sorted out. That saved me a bit of time since I am not overly familiar with coding and that end of things.
