Tyche Lacquer review for Swym Wishlist Plus

I have been having constant issues with this app. I will watch the activity banner show constant updates on an item, view the report and it will not reflect the wishlisting activity that I am seeing. The wishlist takes hours, sometimes days to update and when I contact support they tell me everything is working fine on their end. I have contacted their support multiple times about the wishlisting button not showing on the product page and they keep telling me it's due to cookie settings. I can understand that, but I get numerous complaints from customers across different browsers and mobile that the heart is visible, but the wishlist button is not. I experience this on two different browsers with cookies enabled. I do not experience this on other stores that have a wishlist function. This apps only purpose is to help me figure out how to proceed with stock and it is not fulfilling it's purpose. I've also tried the app across two different themes and am experiencing the same issues.
