Tinxy 2 node device does not retain power state

I have a two node device. I have not connected to a physical switch.

In the app I have enabled Restore state on power

But after power is back after an outage, the app displays switch in ON state, but the my ceiling light is OFF.

In the app, I need to turn off and then turn on the switch for the device to work

Please advise a solution or fix

Please call customer care and ask them to upgrade to v7.6
