Problem - trying to record a show from IOS or Android

I’m attempting to record a show from the Plex app on iOS and Android, however, it’s not working. This happens locally on my home network or remotely.
From iOS app, I receive an Response Error 400.
From Android, touching the record button doesn’t do anything.
The only time recording works, is through the web.

Server Version: 1.9.7.4441
Windows 8.1
Android App Version: 6.7.1.2498

p.s. I apologize for people that have read this post multiple times, I wasn’t properly reporting this problem.
