[Avid-L2] Dynamic Media Folders (DMF) on Mac

My story is titled:

"No Fun with Dynamic Media Folders"

Let me begin with a short rant:

All I have to do is teach this feature and, over the years, without fail, I always have problems, and cannot produce a demonstration that works as advertised. Does anyone actually use this on a production?

SYSTEM: 

- Mojave 10.14.6 on 2018 MBP; 32GB RAM 

- MC: 2021.2.0

BACKGROUND: 

- Source files: .mov (H264).

- Issues (detailed below) occur whether set to UME or Autodetect. 

- I've tried with a New User and a New Project. 

- I've tried recreating the DMF Profile multiple times. 

- Profiles tested: 

a) Copy, then Transcode to DNxHD LB 

b) Copy, then Transcode to ProRes Proxy 

c) Copy only

ISSUES + EXAMPLE CONSOLE MESSAGES:

1.

From Friday 2/26 — Before upgrading from 2020.12 to 2021.2:

ISSUE: Profile is set to Copy and then Transcode to DNxHD LB.  It would copy 5 files and then fail (Red Circle Icon) on the Transcode to DNxHD LB; sample error message below:

------------------------- Start DMF -------------------------

Feb 26, 2021 4:02:26 PM(18)SEVERE: Failed to setup chained feature toggle from /AvidMediaEngine/AMPPlugin/Enable_DNx to /AMPPlugin/Enable_DNx. Second toggle is not registered. com.avid.dmfservice.WSLoggerResource:putXML

------------------------- End DMF -------------------------

2.

From Saturday 2/27 — After upgrading to 2021.2:

ISSUE: Profile is set to Copy only. Over multiple attempts it has varied from copying between 0 and 2 files out of 5 before stopping entirely (Red Circle Icon). Three different messages are created per file (below):
