google cloud platform - GCP Shared VPC : a subnet is not shared from host project to service project

Question

I am running a basic test with GCP Shared VPC on my test deployment.

I would like a suggestion to see if I missed something or this is just some glitch from GCP:

• I have a Shared VPC host project and 3 service projects
• only 2 subnets over 3 are actually shown as shared on the Console and via gcloud command gcloud compute networks subnets list-usable --project [project ID] from one of the service projects

Background:

• there is no organization policy neither restriction,
• I have enabled the host project and attached first 2 service projects, everything was OK
• I granted individual subnets Compute network user roles to 2 users (that are also project owners of each service project)
• I have created a couple of new users with cloud identity in the same organization
• assigned project owner to newly created users for a new project and granted Network user for 3 shared subnets
• Consider I am using the free 300$ trial, but I don't think it would impact just one subnet over 3

Thank you

EDIT : I tried adding network user role to the host project itself for the service project owner user and I can see all shared VPC subnets.

I think this may be a problem then of how the roles are applied (even if I verified them for each subnet) or simply a problem of subnet roles vs project roles
