you can ignore those insights but you cannot remove/clear them
you can rediscover/resync your devices and hope this improves the report
can you tell more on the insights reported ?
the output may be less incorrect than you think
I've see insights about allowed vlan 1,2 does not match allowed vlan 1-2
although our interpretation of this output is as matching , this is NOT the same in comparison
the process simply compares output of commands and so above output is not equal
second example is speed and duplex with provider equipment in between (not dark fiber)
speed and duplex on both sides are negotiated with the provider equipment
but CDP and inventory insights checks the state on the end-to-end connection
