Remote command seek forward (or backward) does not work

Question

I want to be able to seek forward and backward from the lock screen. The code is pretty simple:

MPRemoteCommandCenter *commandCenter = [MPRemoteCommandCenter sharedCommandCenter];
[commandCenter.seekForwardCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent *event) {
    /// seek forward
    return MPRemoteCommandHandlerStatusSuccess;
}];

[commandCenter.seekBackwardCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent *event) {
    /// seek backward
    return MPRemoteCommandHandlerStatusSuccess;
}];

However on the lock screen the playback progress view is not seek-able.

Here is a similar issue, but I need to use MPRemoteCommandCenter (to disable some of default controls). May be somebody can help us both)
