Digital channel skill group assignment drift in AU-1 BYOC

Just noticed that skill group assignments for digital channels are not persisting via CLI in AU-1 BYOC. The pipeline runs successfully, but the changes revert after a few minutes. Using Genesys Cloud CLI v2.1.0. Config below:

resource "genesyscloud_routing_skill_group" "digital_sg" {
 name = "Digital-Support"
 channel_type = "DIGITAL"
}

Is this a known limitation for digital channels in BYOC environments?
