Problem Confirming ISA Declaration

Yesterday evening I wanted to deposit some cash into my ISA, there was a confirm ISA declaration, which I read and agreed, went to ‘Confirm’ only to see a Please Try Again error message multiple times.
This was about 10pm yesterday, I was only at 20% ISA utilisation so wasn’t much of a concern but if I was at 99% utilisation it would have been very frustrating.
Of course it works perfectly this morning. Hope this didn’t affect many people able to utilise towards 100%.
What was the problem here?
