Can't upload photo to whatsapp

Hi,

I got an Iphone 12 pro with iOS 14.4. When I take a picture with the default camera app and trying to upload it to WhatsApp the icon of WhatsApp isn't their. Their are alot off other Apps but WhatsApp is missing. Already tried:

1. Settings > Screen Time > Content & Privacy Restrictions > Photos > Make sure it’s set to “Allow changes”
2. In the app you’re trying to grant access to your photos, try accessing your photos again; It should prompt you to give permission; Accept
3. Now back in Settings > Privacy > Photos, you should see the app and you can give it Read/Write permissions, for example
4. If you still don’t see the app in Settings > Privacy > Photos, here’s another trick that may work (this worked for WhatsApp): Take a screenshot; Click share; Share to WhatsApp; If prompted, accept granting permissions to access your photos; At this point, WhatsApp was already able to access the photos, no need to go back into Settings > Privacy > Photos
5. Deleted WhatsApp and reinstalled it.

Just checked all the settings with my 11 Pro and they are all the same.

What can I check more?

With Kind Regards,

Smeets
