    I am facing a strange problem with my primary whatsapp. Once I swipe it shut, no notifications come till I open the app to check so many a times I don't get to know for hours that someone has sent a message.

    What is most odd in this whole thing is that the parallel WhatsApp on the same phone is working perfectly!!

    I am on Android 9 / Oxygen 9.5.11

    Instrument is 7 pro.

    any help deeply appreciated.

    I am facing the same. Nor delay per se but I don't get notifications until I open it.

    maybe this can help or the issue is because of this

    go to settings>battery>battery optimisation>then click the 3 dots in the right top corner for advanced optimisation>and then disable deep optimisation

    Like Gangesh said, the OxygenOS have a very strict politic regarding apps using RAM, so the battery optimization is very agressive.

    You can disable all together, or you can disable some apps.
