Alita Pleat review for Beast Currency Converter

I just installed this app yesterday and after following the instructions and settings it made all the prices of my product pages have an error and not showing. I immediately reversed the settings changes and deleted the app but my prices are still not showing, my web developer was also not able to resolve this. It's a big issue for this to be happening just before the weekend where I have highest traffic and a terrible experience for us. I have emailed support on this but issue has not been resolved as of time of writing.
