Streaming and Polygon paper and live credentials

When using I use my power (aka v2) paper credentials to receive streaming quote updates from Polygon, I’m getting the error I am getting Invalid Polygon credentials, anybody having this issue? both with live and paper credentials.

Are v2 paper credentials valid for Polygon use if I also have a v2 live account?

Today I used my Paper credentials (v2) and it worked with Polygon alright. I must have been mixing v1 and v2 credentials… Or having a bad day…
