Had this problem for a while now. It started on my Huawei Mate 20 pro and won't work on my Pixel 5. I'll ask.. "send a WhatsApp message to Julie Moby" (my wifes contact name) and always get a reply saying that... Julie Moby is not in WhatsApp contacts.... Same result with any contact which is in my contacts/WhatsApp contacts. I can easily send an sms message using the assistant but prefer to use WhatsApp.. Can anyone help please? Thanks,David.
