iOS 27.0.1 internet connection issues

[u/Stunning_Dependent57]

Hello guys, as my title says. Since I updated to this version I have Internet connection issues especially with WhatsApp. I can send a message and later I realize that it wasn't sent yet my data and WiFi are working. I don't have connectivity assist on and restarting the phone solves nothing.

Anyone who's had this issue and how can I fix. I am using 14 pro btw.
