natwest have withdrawn access ...

natwest have withdrawn access to my account statements from my yahoo. nice of them to tell me so. they’ve just vanished and natwest are no longer in yahoo’s list of addable financial institutions. and i can’t use natwest’s own online banking most of the time because they’ve deemed my chosen platform not secure enough. is it reasonable to change my bank because i’m fed up with the crappy online offerings of the one i’m with?
