I have complained about this issue before. I have been using the app for 5 years now. I never had a problem getting notifications at all. A few years ago I got a new phone. Now I don't even get any notifications. Despite the fact that I did everything you told me to do. My phone is Huawei P-20 lite. My WiFi is working brilliantly. So the problem isn't there. I have friends who uses the same kind of phone. They have the same problem. What am I supposed to do?
