toLocaleString polyfill causes regex error

Error: Invalid regular expression: /[\s\S]{2}(((((((())))))))[\s\S]{1})/: Unmatched ')'

This happens on all browsers that require the polyfill. Using version 1.2.5

Happens to me too.

Did you try to call Intl.__disableRegExpRestore() as mentioned here and here?

This also happened to us on Android in our React Native app. We used this code to fix it on Android, but do nothing on iOS:

if (global.Intl.__disableRegExpRestore) {
  global.Intl.__disableRegExpRestore()
}
