Users are experiencing problems logging into the ADVFN and iHub apps after upgrading to iOS 7.
The symptoms are that the put in their username and password, but when hitting Login nothing happens. This seems to affect all types of iPhone/iPad.
We are working on a fix, although it is not currently clear whether the app will need to be updated to fix the problem.
For the time being I would recommend using the site directly from a computer or your mobile device (mobile site).
