For 2019 version including Ps, for some reason R2L features for Dhivehi language does not work.
I'm back to 2018 version due to this and really miss the neat features available in 2019 version.
Hope they issue an update to fix the issue.
Sorry to hear that these features are not working in version 2019. I would request if you post it on our UserVoice page (https://illustrator.uservoice.com/) and share the link here so that others can also upvote it.
This is the best way of communicating with the Engineering and Product Management teams regarding issues and suggestions so they can be implemented in future releases.
