Kanisk Poddar , via OnePlus 6 , Sep 30, 2020 : Hi! I am having problems in switching calls. I am unable to hold and trandfer calls while talking to someone. If I am already on a call and want to accept another call and keep the original call on hold it's displaying "Can't hold calls" and then even if the original call is disconnected I am not able to accept the new call. I've had this problems sometimes before but not on a regular basis, until recently.
