We've been using Trello for a while and up until last week when someone updates/created/deletes/moves any of the Trello cards anyone logged into Trello sees the changes immediately without having to refresh the page.
However since last week we're finding this is no longer the case. Now if, for example 2 people have the same Trello board open, and one moves a card, the other person does not see the card has been moved unless they refresh their browser page.
We normally use Chrome, but have tried other browsers since last week, and are still having the same issue.
