Internet banking not working properly

The FNB internet banking does not work properly on my tablet (Samsung galaxy S4 tab). The pay button when transferring money from my cheque account to a beneficiary does not work. When I click on the pay button nothing happens. I was not that surprised as this was not the first time I experience such a problem with the pay button, i had the same problem late last October when i wanted to pay one of my beneficiaries as I did not have my notebook. I suffer every time I am travelling and as a result i could pay my beneficiaries.<br> The desktop version works fine all the time. Why different versions? Why redirect me during login and force me to a version that does not work?
