Oshen review for Selfnamed: Cosmetics on demand

I really like the potential this app and platform has - the products are beautiful. But the customer service is really really slow and there are still a few bugs to be fixed. The currency is the same even if you switch location, so if a product is 5 Euros it will also show as 5GBP and 5USD on my bill which doesnt make sense and I'm unsure how much I'm really being charged. My customers keep getting angry because their shipping tracking numbers arent sent to them and their order status remains on "preparing" and on my end of it I also can't view any customer shipping tracking numbers so I can't help them.
