I've recently received the android Pie update on my Mate 10 Pro but it seems the Mail app has lost a useful functionality. The selection tick boxes on the left of the emails have been replaced by tiny blue dots. But when you tap on these it just opens the email. In other words you can't select emails for deletion or moving. Is there a way around this? It's not a game changer ad I'm happy to have received the update so soon, its just a bit of an oddity.
