I've tried both approaches to edit video in Audition. Dynamic Link is broken in the latest beta build.
Steps to reproduce: 1. Create any sequence in Premiere Pro and select Edit/Edit in Adobe Audition/Sequence
2. Select Dynamic Link as the video option
Result: Audio tracks open up but there is no video and an error message appears in a popup panel that says Dynamic Link Server not found. If you choose to use DV video you get an immediate fail. Expected: This has worked for years. It should still work. System info Application: Premiere Pro (Beta) v220.127.116.11 OS: macOS v11.4.0, RAM: 8.00 GB, CPUs (logical): 8
