iPhone 17 WhatsApp online/last seen privacy settings not selective.

I’ve just got a new iPhone 17 and have installed WhatsApp. When I go into settings and privacy I want online and last seen to be seen by my contacts with a few exclusions. However, when I exclude a few people or even one person I then can’t see the online or last seen for most of my contacts and they also can’t see me on their phone which means I have to choose to be seen by all contacts which isn’t what I want. I didn’t have this issue on my last iPhone. I’ve taken WhatsApp off my phone and reinstalled it a number of times but still have the same problem. Any ideas?
