Paper Plus Cloth review for Geolocation

As per an email from Shopify that this app was going to be added to shops as of Oct. 4, I decided to download it ahead of time and right away it caused issues for customers viewing my website outside of Canada. It displayed incorrect prices that were converted TWICE! So if I had an item that was $45 cad it should have displayed $37 usd, but instead converted it again to $29.50 (the US equivalent of $37cad). How does that even happen? I fear for everyone who will find out bad this app is on Oct. 4th
