Do you want to request a feature or report a bug?

What is the current behavior?

Which versions of React and react-helmet, and which browser / OS are affected by this issue?
Did this work in previous versions of React and/or react-helmet?

 "react": "^16.11.0",
 "react-dom": "^16.11.0",
 "react-helmet": "^6.1.0",

There is no solution other than react helmet async.

There is no solution other than react helmet async.

react-helmet-async package works well.

I don't get why the issue in this repository (react-helmet) should be avoided by ditching this (react-helmet) entirely and switch to another library (react-helmet-async with different owner of the repo)

Can't the issue be fixed in this repository with an update? Should we all just stop using react-helmet? I mean if another package made it work (react-helmet-async), why can't also this (react-helmet) change to React's standard recommendations?

What in the world?

Is this library maintained anymore? Last publish was 3 years ago.
I think the least the maintainer/former maintainer could do is update the README and redirect the new users to a suitable alternative.
