I'm sorry, I do not have a solution to this.
But on the topic of WhatsApp, how do you Grapheners deal with the backups? I do not want to add a Google Drive account to my phone, nor do I want to root. Does this basically mean that I cannot have backups of my chats?
I'd rather use something like Signal, but we all know how it is with these apps. I can't persuade everyone to just move away from WhatsApp.
