Hi Denis,
Hope you are doing well,
We understand that it has been a while since the request. There are different stages to the implementation as it would involve the compilation of the required domains and the categories that should be added. On completion of the development, there would be the vigorous QA grill on which this would be tested on the various platforms that support the web content filtering.
These stages would be handled by different teams, and hence, we may not be able to provide you with an ETA on this. We would like to apologise for the time taken on completing this. We shall have you added to the feature request pool and keep you in the loop with updates regarding this.
We sincerely hope you and your loved ones take care and stay safe. Have a great day!
Cheers!
Jeff Black
