I chatted with WhatsApp support bot and tried everything they told me without being able to resolve the issue. At the end I shared the link to this thread and this was their reply:
”I understand that this feature used to work for you, and it's no longer working after a recent update. I apologize for the inconvenience this has caused.
Thank you for sharing the link to the Apple discussion thread. I'll make sure to pass on this feedback to our team, so they're aware of the issue. We'll take this into consideration for future updates.
I appreciate your help in bringing this to our attention, and I'm sorry again for the disruption to your experience. If you have any other questions or concerns, feel free to ask.”
Hope some WhatsApp human actually reads this and does something about it. Maybe if more people write to them about the issue it would help.
