Upgraded from v132 to v137 since the changelog said QoS is working again. Cleared NVRAM and reconfigured from scratch. QoS does appear to be working properly now (using 1 WAN interface) and everything appears to function normally, except that the "Bandwidth Graph (Inbound)" constantly displays 100% of the traffic being in whatever class is set as "default" in the QoS > Basic Settings page. The other graphs (Connections and Outbound BW) appear as normal.
