palmer//harding review for MLV Auto Currency Switcher

I've had the app installed for a while and have encountered the same problems time after time. When switching currency, the rounding rules that you set up in markets (rounding to 0 decimal points) doesn't flow through to this app. So for a currency like Kuwait Dinar, instead of 145KWD, it shows 145.760KWD - which doesn't look great or professional. This applies to all currencies - ignoring the decimal rules you can set with Shopify, so USD shows as $450.00 for example. I have contacted support numerous times and they either say it's a shopify problem, or that they just can't help me. Additionally, they are great at the initial customisation setup, but EVERY TIME you update your theme, their customisations are removed, and you have to reach out to them to edit it for you again, which has become extremely tiresome. It is such a shame as this app is generally good at what it does, but the creators seem to have no desire to refine it to make it an excellent experience for shopify users and their customers. I will be looking around to find an alternative.
