Can not receive WhatsApp messages unless I open the app. I have a Huawei P20 Lite with Android 9, EMUI 9.1.0 and WhatsApp 2.19.253, which is the latest version. As I wrote in the title, I can't receive WhatsApp messages, after many hours of researching I didn't find any solution for my problem. Since the latest update I can't seem to open downloaded PDF's. They show up on my scroll-down list at the top of my phone, and it says they're downloaded. However, when I try to open them, it doesn't work, and I can't find the files anywhere else. *** EMUI12 Problem Thread (HUAWEI P20) RealDexxo Senior Member.
