iPhone SE prompts incorrect Apple ID for WhatsApp update

Whats App

update Issue

When I now

try to access Whats App on my iphone SE either via the app or the App Store, I

get a message saying that” this version of Whatsapp has expired, please go to

the App Store and update it “

“Your update

will be free of charge”

Below there

is an invitation to Update Whatsapp.

When I click

on this I see this message

“Your Apple

Account

(………@btopenworld.com)

or password

is incorrect, please try again”

This email

address is one that my wife uses on her iphone and that account is also accessible

on my phone as a 2nd email account.

My email

address is   ……..@btinternet.com and as

far as I know has always been the only address associated with the Apple

Account.

I have

recently changed my Apple Account pass word in an effort to sort this out which

was confirmed with an email to me (@ btinternet.com)asking if I had made the

change.

I want  my own email address in my Apple Account and

in an effort to solve this issue named it the  Primary account.

I know my

Apple Account pass word but not one that may be associated with with

btopenworld.

I have tried

to sort this problem by going on line but the options and answers  are a bit daunting when I see that the wrong

decision could stop access for 30 days or loose data etc.

The bottom

line is I want my email address ( named as Primary or not ) and password to be

what is used for my Apple Account

Thank you.
