Latest Windows Insider 19654.1 and Edge releases with Netflix

Hey all,

My Dev PC has just upgraded Windows Fast Ring to 19645.1. Since this upgrade neither current Edge Dev Version 85.0.538.0 (Official build) dev (64-bit) or Edge Stable Version 83.0.478.45 (Official build) (64-bit) will stream any Netflix programs. On my Windows stable PC, both these versions of Edge work fine with Netflix. On the Fast Ring PC, Firefox works fine with Netflix.

Has anyone experienced this behaviour?
