Currency Converter apps suddenly stopped working

[GalacticGlowlig]

So I installed a currency converter app called the best currency converter on my minimal theme and it was working perfectly the first few days but now all of a sudden when I logged into my store today I immediately noticed that the app is not working and the currency is not being converted and there is no drop down menu allowing us to choose a currency. It's like if the app is not even there. I contacted the app creators but haven't received a reply yet. I also tried reinstalling the app but the problem persists. I even tried to install another currency converter app but again it shows nothing. If anybody is experiencing the same issue or knows something about it please let me know. Thanks.
