OneX Mobile on iPhone cannot use Supverised Transfer

[tosta]

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.
