Thanks for your reply. Its a mystery how it is operating now. When I delete multiple messages they go in to the Trash (Bin) folder. I then do Empty Bin Now and all but the latest message is deleted from that folder. Although as previously checked the folder is actually empty when checked on the Gmail via Chrome means of access. Also on the tablet, in the left hand folder pane, the message count for the Bin folder disappears suggesting all messages have been deleted from that folder. But that last message remains visible in the Bin folder view and remains there for some time before it disappears. I'm not sure why it disappears later, maybe some other activity on the app triggers it, or maybe its a "housekeeping" type activity. I suppose I can live with this new operation of the app but its frustrating to not know what has caused it, that is, is it a malfunction on my tablet or is it a change introduced by a recent app update from the developers?.
