Some Apps not working on IPhone 13 Pro max

Hi all,

I have just upgraded to iPhone 13 pro max. I have transferred all my data and apps from iPhone X. However, I am having trouble with using three apps, YouTube, YouTube Music and WhatsApp. Every time I try to open these apps I get a message on the apps asking me to check my internet connection as for some reason they can’t seem to connect to internet despite already being connected to both, 5G and wifi so I certainly do have internet connection.

I have tried many things including; switching between 5G and wifi to launch the apps, turning the plane mode on and off, restarting the phone, removing and re downloading the apps but so far none has been successful! Every other app works fine and I am perfectly connected to internet. Only those three apps seem to think I have no internet connection. Seems like some sort of a bug.

I have also updated my phone’s software after transferring my old data.

Thanks heaps in advance.
