In my case it's the list of upgrade instruments to choose from which is always empty (no, I do have plenty of E-upgrades of all kinds.)
Calling web support and having them "manually" process the on-line sponsored upgrade does at least save me a trip to the airport to write the bluey. Although it's not a great time saver, those cretins take 30-60 minutes on every call thanks to their rudimentary grasp of English and apparent incapacity to do anything other than call the next cretin up the chain.
And as for actually fixing the bug, not a chance. Anyway there are 112 pages of other bugs in line in the FT sticky about dot Bomb
