Tielka review for Bold Subscriptions App

Update: the issue has still not been worked out, as per response from Bold. Unfortunately, there is a serious glitch in Bold's currency conversion in the subscription app. Bold has still not been able to resolve this after over a month, and it's causing us ongoing issues for our customers and our accounting. It's been frustrating as they are taking a long time to answer, I've been passed around and had to answer the same question by different people twice, and now the person who I had been speaking to has gone on holiday and I've been passed to someone else. The glitch is that when customers have their subscriptions changed from the backend they then get charged the amount set by our store, only it's in their original purchase currency. So if the price in our store is 49.60 AUD, and the customer originally purchased their subscription in USD, when we swap a product for them, they start getting charged 49.60 USD instead of 32 USD (which is the correct conversion rate). It's a massive issue, as we changed the products in ALL our customers' subscriptions (the customer was effectively getting the same product, we just had to create new SKUs in Shopify and update the subscriptions accordingly), so this is now happening to around 25% of subscription transactions, as these are in USD. Also, when we change products in the backend, some customers are being charged for postage and others aren't - we have no idea why.
