Was once so satisfied with TB ... for years. But a few updates ago TB simply stopped polling all my accounts other than the default account on startup. (If I click 'Get all mail', it does poll all accounts, but I really need it too poll all accounts on startup, AND periodically, neither of which it does any longer.) I've changed no settings. I'm not particularly tech challenged. But unless I can resolve this, I have to go to an alternative client. Hope folks know what is going on. It was a great app. But it no longer does what it used to.
