NRF connect doesn't reconnect when phone bluetooth is turned off and then back to on again

[Prasad]

I connect to my BLE peripheral device using NRF connect app. While in connection, if I switch my phone's bluetooth off and turn it back again and then try to connect to my device then it doesn't connect. If I go to the "scanner" tab and do a scan, I observed that my device is advertising. When I press the connect button from the scanner screen then NRF connect connects to my device.

Why is NRF connect not able to connect when I press the connect button(upper right corner button) on the device's tab? And what happens when I do a scan, after which I am able to connect to my device?

OS: Android nugget on Motorola C.

My nrfconnect application version is 4.12.0, I think this is the latest available. Yes, I am waiting long enough. Actually when I turn off bluetooth, "enable" button appears on nrfconnect and not the connection status. My peripheral device also indicates that it is in disconnected state and it is advertising.

I tested this issue on Motorola E phone as well, this issue doesnt occur on Moto E.
