To anyone who might help, I tried to use some apps to set my second whatsapp account on Blackberry Aurora. I had to quit parallel space, for there were too many advertisements. It also duplicated notifications in screen by showing them fully visible, even though I set the option for not showing their content. Other similar apps drained too much battery. I finally tried with the guest account option, but I have to remove it completely to come back to my original one. I kindly ask if there is a way to maintain a second account on the device, so as to shift between the two accounts to pass from a whatsapp account to another. Any suggestion would really be kind, thank you
