According to Twitter spokesperson, there is some technical issue in sending links via direct messages. Users have also complained about the problems they are facing in sending links in direct messages, so it’s clear that this is in fact down to a bug. The thing which is not clear, is when this issue will be resolved, though we presume Twitter is working on it now.
Earlier this week, Twitter revamped its direct messages — one of its oldest features — giving users the choice to receive private messages from any of their followers.In the past, twitter users were not able to send direct messages to those whom they follow, but are not followed back.
