I’m using the simple facebook and whatsapp app. In my profile, as always, i have everything checked (VPN, Proxy, TOR, Literal IP addresses, safe search) except ad block.
I have less problems with facebook, but with whatsapp the situation is very bad, sometimes i receive messages late hours, some days i must to switch to the mobile data.
Why it works with only Proxy/VPN checked? In this case my problem remains.
