It's MBNA miles day. I logged in (from the http not https site, so was redirected to https) and I can see my balance is correct (i.e. the miles have been added), but there is no entry in the 'recent activity' bit.
The loading process for that one page took just under 5 minutes for 100% of the items
If I click to view recent activities, the MBNA transfer is listed. That page loaded quicker (in a worthwhile way, I could see the content) but still took about 30-45 seconds to download all the elements.
I do like the new look and feel - but I hope these teething problems on speed are fixed soon!
