Auto Detect Currency Switch is not working with Premium version

Hello,

for some time we where using the free version of the plugin and everything was working great. After switching to the premium version of the plugin, we found that the automatic currency conversion is no longer working. Can you help us fix this? We notice that there are many more settings and we are interested in which one would be the most optimal for our website. We also use the WP Rocket cache plugin and CloudFlare CDN, if this is related to anything…

Thank you and regards,
Robert
