How can you reset Whatsapp to the read function?

With me came a notification on the lock screen of WhatsApp I could on individual chats the function., Mark as read "then I turned off and asked if someone could please help me as the read function again? She comes.

I have a Huawei, Android device.

Go to: Settings -> Account -> Privacy

And then put a check on read receipts.

WhatsApp Settings> Account> Privacy> Read Receipt / On or Off. At least that's the case with Apple

So I do not know that that goes for individual, but I've probably missed something synonymous.

You can definitely turn it back on under privacy.
