This has been an issue for as long as i've been using iPhone and Android (which is many many years nowCould certainly be that, but I somehow doubt it. I am talking about multiple banking apps throughout many years of Android phones. How can they all be bad on Android?
Of course you did just justify the argument about APPs being better and more refined on iOS as opposed to Android.
Even APPs such as my Bible app has delayed notifications. At noon today, like every day, my iPhone on the dot dinged with the daily Bible verse. My Pixel 8 Pro sitting here as well didn't come through until 12:15.
So ya, I underdstand what you are saying, but it just seems like its a lot of APPs that all do that on Android. How can they all be bad compared to their iOS counterparts?
Mostly noticeable when the phones are just left idle - the iPhone will always ping the alert instantly, whereas the android will either take time or alert when you wake it up.
I've found that if i'm actually using the phone, and a whatsapp message is sent for instance, i will receive at the same time on both devices.
