Yes, @Travis_IOI, I'd like to strongly echo @Ed_ll3's experiences this weekend. Whilst in @mungadungalis's Twitch stream last night I asked if players on other platforms were experiencing the same problems and they did not seem to. So it seems that Xbox is the worst hit. @Ed_ll3 and I are in the UK, but @mungadungalis is in the US, so it's not even restricted to one side of the Atlantic (assuming you have servers elsewhere). In his stream everyone witnessed the same painful experiences that we have both been experiencing. I can't remember the last time my scorecard appeared without having to go to Replan and pressing back several times. I've been getting Disconnected dialogue boxes whilst playing missions. I kill the last target and the Exit does not appear. And sometimes after selecting Replay the screen will lock (with the animated barcode) for up to two minutes before advancing to the normal load screen.
We can only speculate that since you've made the intro level free that the amount of traffic has increased and the servers (for Xbox?) simply cannot cope. This is exactly what happened after the disc release in January.
Fortunately the January issue went away for us, but I suspect that it was because new players literally gave up and moved on because of their terrible connectivity experiences. Consequently server load went down again. We stuck around because we know how good the game is. My concern is that all the new players you've acquired since making the intro free are not going to stick around if they continue to experience these issues.
