Black Lava Vape review for IMPEX Collection Import Export

This App I want to work so bad! It is exactly what I am looking for. I installed this on two of my stores. On 1 store I exported my collection & downloaded it. It came out perfect! I then went to my other store that I need to import it on and this is where I got stuck. When trying to import the .csv file that it created (I did not modify it at all. I simply exported & saved it) it errors out. I get it if I was trying to import a file I tried to create. But this .csv file was created by the app. Since posting this review and submitting a trouble ticket, I have heard nothing from the developer. Changing from a 2 star to a 1 star review.
