When you click "Add New Account" a list of providers will appear with first item in the list already selected, at this stage there is no indication that single click on any item is the next needed action because first item is already selected, so user tries to randomly click many times to discover how this page works. This is really not friendly at all, at least : - when the list appears there should no item selected and there should be an arrow or text indicating that single selection is the next needed action - or retain single selection only for selecting the desired provider and add another "Add" button at bottom which will show the login/password page of the currently selected provider.
Yeah, nothing should be pre-selected, probably.
Fixed by Mufeed Ali with https://invent.kde.org/network/kaccounts-integration/-/commit/1c40dc4f429ec7968e8f0aac1cbe00fbad07b762 in kaccounts-integration 20.12 (there was a merge request lying around that fixed it, which I found while submitting my own)!
