Yacxilan Artwear review for MLV Multi Country Pricing

This is the more stupid app i have ever found ...i cannot understand why you have such good reviews...so i pay for an app to make my work easier ...with MLVeda my work dobles if i add one country ....and like that ....also my stock dobles ...why in the hell would my doble if i change the price in another country ...it doesnt mean the i have doble the stocks....im not a app creator but i have a pretty good idea of how this should work ....add country > add % > click yes ....all prices automatically change for that country ...easy ... let the app do the work ....Now i have been paying 4 ppl to update all my thousands of products for days to come and see that it doesnt work at all as i expected ...My work on my products have doubled ...the stocks have doubled ....this is a waste of my time
