Recieving messages after iPhone restart.
I turned my iPhone off, and a few minutes after back on, but didnt use the phone much, after I got home I updated the IOS (new iPhone). After the updates was done I again didnt do much with it. Then at some point I got a Whatsapp message from ''12 minutes ago''. But when I opened it, it was send like 1 / 1,5 hours ago. I got the message after turning it back on, but before the update. But the message came way after the update. How is this possible?
iPhone XS, iOS 12
