BUCKS Currency Converter PRO++

Abysmal customer service. Virtually none. The responses that do arrive are very slow, not helpful, not followed up. So as long as things are working ok, then ok. But, it's not. First it was working with Shopify's multiple currencies and then apparently it was not. At first the prices showed USD and then they did not. At first the switch from the shop currency to chosen currency was fast, as claimed. Now it is very slow. No response from the app once again. It's been such a waste of time.
