nva-hifi review for Amai PreOrder Manager + Notify

Unfortunately, I cannot tell if this app is suitable for me, or not. The 7 day trial allows me to apply the app to only ONE product. I can't tell anything about how bulk editing works, I can't even know if the 'settings' that I change are universal or product specific. Additionally, the 'pre-order with discount' feature is switched off in the 1 product trial, so I cannot see how that works and how it displays on my site. If I want to know any of the above then I have to immediately pay the monthly fee. Rather defeats the objective of a free trial, methinks. UPDATE - thanks for the reply. I welcome the clarity. In my Shopify dashboard, it still mentions a 7 day trial. Additionally, I received an email from your Customer Success Representative who states "Should you wish to know more about how the App works? we are happy to offer a 1-month free trial if you decide to continue to use our app. Just let me know your Shopify URL and I will make a request to the management for a 1-month free usage. Do you want to clarify, further? FURTHER UPDATE - after removing the app from my store I found that not all the code was removed. This caused problems on my storefront and I had to remove the code manually.
