On march 8 (7 months ago) a user started this thread because a vital feature is missing from Viber.
Namely the posibility to change notification tone and volume of the ringtone.
Is this feature still not implemented today, 7 months later ?
Right now i only use Viber to relay non-critical or "does not need immediate answer" because of this problem.
If i need an answer and need to know that the receiver has received the message i still use SMS because of this design flaw.
Please tell me that you are competent enough to impletent such a basic feature in less than 7 months. ?
