Premier Table Linens review for APO Product Options, Variants

I've been waiting 2 months for the app to fix an issue, they just stopped replying to my emails!!!!. This app is not compatible with Shopify shipping profiles and is NOT compatible with any tier pricing app, we can't do any volume discount with this app installed. they haven't provided any solution to this problem, they are just waiting to release their app update since 2 months ago. After reading the reviews I saw that another user reported this same issue back in September 2020. so there it goes the quality of their support!! Update: They told me that the new version was going to be released during the month of April. Today is April 22 and nothing yet.
