OneX Mobile on iPhone cannot use Supverised Transfer
 

Blind Transfer OK in the OneX Mobile on iPhone, but couldn't do a Supervised transfer. Is this supported?
Tried on Android phone and it works perfectly on both blind and supervised transfer.

Tested One-X Mobile on iPhone and it works by selecting the Add Call then go to Call List then press the transfer icon. Different from user guide but it works.

Which release?
They tend to change such things in every release...
