My phone (Lumia 640XL DS) using Windows 10 Mobile stops getting notifications for some apps for example WhatsApp, Facebook Messenger and Facebook. It's really annoying because I miss a lot of messages on those messaging apps. Anyone experiencing this bug too? It works for a couple of hours after I restart my phone and then I get the bug again, tried even to soft reset my phone but it gets back again... The text messages app works normally and doesn't bug out.
