If that is the only app you are having trouble with, it may be best to contact Meta for support. If there is a bug in the app causing that problem, they are the only ones that will be able to update the app to resolve the issue.

About the only thing you can do on your end is delete the app and redownload it again to see if that solves the problem. If you are using a VPN, you could also try deleting that to see if it is causing a conflict with WhatsApp.
