Poor Website and App

The website and app are just terrible. As far as the website goes, despite re-registering to their new SSO logon, it is absolutely impossible to login. Shocking for this day and age. You would think it went through negative and positive testing before going live!! The app is no better, although at least the SSO sign on works on the app but tried updating my details - even get a message to say details updated, but alas it is still wrong. ..... And try entering a delivery address... The Submit button is hidden by the big delivery "D". COME ON DIS-CHEM
