We added RevenueCat to our app recently and are using the react-native SDK. We have seen the warning “Could not determine price format because price string is incompatible” thousands of times from production users. 

The majority of instances seem to be in the UK, but we have also seen it in Australia, the United States, South Africa, and Canada. 

What does this mean? What is the user impact? 

Thanks,

Jacob

Hi ​@Jacob from Deglaze,

Are you using any custom fonts in your paywall? If that’s the case, it could be that we are not finding the font when displaying the paywall which could cause showing the default one. It’s strange that you only see it in certain countries rather than all or none, are they all in the same app version or are you showing different paywalls on those countries?

Best,
