    WhatsApp only recieves messages when I open the app, I don't recieve messages if the app isn't open, once I open the app, it refreshes and I get a ton of messages at once, I don't get notifications when the app isn't open, anybody else?

    In battery settings and advanced optimization, disable that completely or choose only Whatsapp from the list and "do not optimize"

    thanks guys, it's working fine now, but do you have any idea why this problem development right now? it wasn't present since I've bought the phone or the recent update,and I don't recall changing any optimisation settings, just curious xD

    I'm still having the issue. I've disabled both things, but still just receiving messages when opening the app. I suspect it's related to WiFi, because under lte it seems not to happen
