This is exactly the procedure that I used to add PayPal
On my Tablet, I signed into my PSN Account
Clicked on the arrow next to my Profile pic
Selected the Tab "Settings" - this now opens to another screen
Select "Account Information"
This opens to another page - Dashboard
Select "Wallet"
Now you should be looking at Wallet Funds.
Add Funds to Wallet
Add Credit Card
Add PayPal if this is available in your Country
Click the PayPal box
This now opens to a web browser
You now enter in your PSN email and password
Press Sign In
This now opens up the web page to log into PayPal
Enter in your PayPal email and password
Log in
This will open another web page from PayPal
Welcome....
Information from the merchant
Sony PSN....
Pay with (your Bank Name)
At the bottom of this page is
Agree and Continue
Press that and you are now done.
It takes you back to the Dashboard
PayPal now has a tick and shows the email address that is associated with your PayPal Account.
