Yeelight rgb bulb to Smartthings - help needed

In the app (not classic) there is an option to add Yeelight. I have an rgb bulb configured in my Yeelight app which i currently control via IFTTT but wanted to add directly to Smartthings via this new option.

When i go to add Yeelight the app goes through the whole process of connencting to my Yeelight account successfully but the last window just says i can now control my Yeelights in Smartthings but does not list any devices, so i am at a loss of how to actually add each device - is this actually working and then how? Am i missing something?

I am connected to the Singapore Yeelight server - do i need to be connected to another server to have this working?
