Yahoo messenger - not receiving messages on sign-in

Hello, I've had a search but with no success.

The problem I have with Yahoo messenger (on a BB 9790 on Orange in the UK) is that if a message is sent to me when I'm signed out, it does not get sent to me when I then sign in. If I long into my yahoo account, I can see the message listed under conversations, but it never makes it to my phone.

When I am signed in it works fine and I have no problems with it. I am using it to keep in touch with friends on iPhones etc, so can't use BBM.

Has anyone else had the same problem as me? Did you manage to sort it?

Thanks in advance for any help.

get an apps like whatsapp
its a more functional multi platform messenger.

your issue seems like a common problem. i googled it, and there are a lot of people with the same issue.
