Own WhatsApp tone does not work with every contact – Android-Hilfe.de

Hello everyone, I’ve had my own WhatsApp tone for years. I also copied and assigned these to Notifications and Ringtone. Works great except for my wife’s contact. The standard tone of the A72 always comes there. It works for everyone else too. I don’t know what else to adjust. The other way around (she has the same cellphone) it is exactly the problem. I’ll go crazy. Would be very grateful for a hint. Thank you, Andreas
