Hi,@Vishlamba 

Thank you for posting on our business forum.
 

Could you please navigate to Global View > Settings > History Data Retention and check whether the Client History Retention function is enabled? If it is currently disabled, please turn on this option.

Additionally, we would like to confirm whether this issue existed before you upgraded your Controller firmware.

If the issue still persists after the adjustment above, would you be willing to conduct a comparative test by downgrading your Controller to the previous version, to help us verify whether the problem is caused by the new firmware?

Thank you very much for your cooperation and patience.

Hi this is definitely not a new issue I had seen this since 6.1 FW was released on all my controller OC200 and OC300 both and it doesn't happen all the time, and not to all clients. its like hit and miss, still if you would like to downgrade ill be happy to do that. As this feature if very important for me as I use a lot of automation devices that work wireless, so let me know which FW would you like to downgrade to and which one OC200 or OC300 as all if my controller are running  on 6.2.0.17. Thanks
