Microsoft started forcing Windows Live Messenger users over to Skype nearly a year ago, and it has been a painful experience. If you use Skype frequently for messaging then the missed messages, out-of-sync chats, and blasts of old messages are a regular and irritating experience. You can use Skype on a desktop PC to chat to a friend, but when you move to a smartphone or tablet the conversation doesn’t always sync properly or the mobile apps bombard you with notifications for old chats. We know that as users have started using Skype on multiple devices, they’ve had difficulty keeping conversations in sync, admits Microsoft.
