undefined is not a function (evaluating '$GOPS.f(toObject(it))')

[helloagain-dev]

I am getting the following exception with react-native due to the following change https://github.com/zloirock/core-js/pull/539 in core-js 2.6.6.

This only happens on Android running on the device. If I debug the app with chrome, the crash does not happen.

Fixing the version of core-js to 2.6.5 resolved the issue.

It's a conflict with an alternative not completely correct Symbol polyfill, see #550. A fix for this already added and will be published ASAP.

Done.
