Error 4300 on app

[brakeman]

Had to reinstall iOS on iPhone 5s and now get the dreaded error 4300 message. Have deleted app from iPhone storage and installed completely new copy but always get the same error. Any tried and tested solution please?

Hi @brakeman 

Just a suggestion for you to try before tomorrow.  

Try going into the My Vodafone application settings and selecting reset the application, also go into your phone applications, scroll down to My Vodafone and click storage > clear data > clear cache.  Reboot the phone and try logging in again using a mobile data connection, this is needed to locate your account.

I hope it will work for you and you have access to the Application.

Hi Ann, this is iOS rather than android. On the 5s you can either offload the app to the cloud and redownload, or delete it altogether and download a clean copy. Neither of those worked and of course it's not possible to get into the apps' s settings at all until it's registered and up and running. So I will wait till tomorrow evening when I am promised there will be no problem. I'm not overly confident but the adviser was so we will see.
