Error after Update to version 8.0.14

Did everything but still facing it.
It works on one browser and not in another.
So problem is not with bench rebuild.
I’ll paste the console error to let you know exactly about the error:

@Ujjawal you need to upgrade your browser so that it supports ES6 syntax. Though, we are releasing a new build system that will avoid this later today.

Alright.

Thanks for the support.

Is the error solved?

Has the error solved
