Issues with G2 Review Attributions and Campaign Credit Since Move to Self-Service

Has anyone seen issues with G2 and review attributions to campaigns since they moved to self service? I see reviews coming in that I assume are attached to certain campaigns, but the campaign itself isn't getting the credit. Another was with the Rally Review campaign getting credit, but not sharing with rep it came from. I've raised this to our CSM, but wondering if this is just growing problems with their new roll outs this spring.
