@MaciekMa: Does this issue occur while connected to Wi-Fi, Mobile data, or both? In the meantime, please head to Settings > Apps > WhatsApp > Battery > Unrestricted > Mobile data > Allow background data usage (On).

Hey there and welcome to the Samsung UK and EU Community Customer to Customer Forum

Sorry to hear of your issues.

When you got your A55, did you bring WhatsApp over via SmartSwitch or did you install the app from the Google Play Store?

If via SmartSwitch, recommend you uninstall WhatsApp then go to the Play Store (don't simply select reinstall after uninstalling), search WhatsApp and reinstall
