I asked @nayelyz to check on this two weeks ago because we are seeing reports both ways in the forum now. Some people saying they had to delete a custom groovy DTH before the edge driver was accepted and others saying they didn’t.
I am starting to wonder if maybe it varies by model number now, but I just don’t know. Or maybe there’s even a flag on individual accounts for specific devices that have been automatically migrated. It still feels confusing.
