I have had an iPhone 7 for several months. I am not very competent at using it and use it as little as possible.
I subscribe to a WhatsApp group, and have been doing so for several weeks with no problems.
But yesterday WhatsApp told me that my version of WhatsApp has expired and to go to the App Store to update it. But I then get the message that it cannot connect to the App Store. On attempting to update it, I get told my iPhone isn't connected to the internet. In the past I have been asked for a password to access the Apple store, but not this time. How should I proceed?
FWIW, I have recently been upgraded to BT's Digital Voice (spit!), if that's relevant, which it probably isn't.
