Plex for iOS (iPhone & iPad) give errors every time I try to schedule a recording

While I can schedule a recording just fine through Plex Web, any time I try to do it on iOS any device, I get an instant “Uh oh” error that says error response: 400. Any idea why this is happening? Would like to be able to schedule from phone or iPad. Also, when is this capability coming to Roku app? I know it already came to Apple TV app. Thanks.

i’m also having the same issue
