All Jigsaw Puzzles review for Easify Custom Product Options

Installed this app today as I was looking for a seamless and better process for providing gift wrapping and offering a hand-written gift card with products and I spent several hours setting all of this up. It looked great and I was really impressed with the app however I discovered an issue with the app. By linking a product with required options as a custom product option in this app (such as a custom message to hand-write on a gift card), this app was allowing it to be added to cart with no message field populated so it was not honouring the adding to cart process and requesting that required fields are populated first. That itself wasn't really the issue though. It's an oversight by the app developers so I brought this to their attention only to spend 30+ ridiculously painful minutes of my life trying to explain what the issue was to a customer service rep who completely did not understand, grasp or get what I was saying - even with accompanying with screenshots and highlighting fields/problems. It was completely stupid and one big waste of my time. So I am leaving this review to warn others that this app will add products to cart without required fields set (if you are linking an actual product to a custom option) and if you need support, it is absolutely abysmal - don't waste your time! EDIT Since writing this 1 star review, I was followed up my a product manager who was much competent and understanding of my issue who worked with me to find a way to achieve what I was trying to do. We did identify an issue where you can't use non-product-linked custom options with products that are on discount however I believe that is one of the millions of bugs with Shopify itself rather than this app. I am changing my 1 star review to a 5 star review as a result of this follow up dealing with competent members of their team that worked with me to find a solution for our store. They also offered an extension to the trial as a result as well so great eventual service.
