Targeting 1st Party Data using Customer Match in GDN

Hey folks, did Google recently change policies on sending data out from LiveRamp to GDN/Customer Match to restrict targeting to Search, Shoppable, Gmail and YouTube only (no Display Network)? Is this something anyone has experience with?

Up until last month we were able to send to the customer match liveramp destination for GDN, but it no longer appears to be the case?

Some support docs below, seems this has been going on upwards of 6 months, but perhaps we were grandfathered or fell through the cracks until now? I didn't get any notification of this until we tried sending new data over today.
