Hi,
regarding your page which loading to much; as per my finding your data is flooding in your CX module thats why prime infra page keep on loading. check whether your module policies utilization and memory is OK if yes then contact to TAC.
regrading policy: does your policies keep working in your apply network configuration if yes then copy from there if not then your module is malfunctioning
