since the update to TB 52.1.1 I get a different mail alert behavior 1) there's a new mailbox animation, sliding a notification on the left border upwards. How can I disable that? 2) TB now sends me mailbox alerts for a folder where I disabled mailbox alerts - that's a popup on the right top, telling me about new messages from facebook and linkedIn, which went straight to the folder SN (social networks) and which I hardly ever read Is this a TB bug or something that can be disabled?
