Our substitution profiles engage about an hour before game time, and there is another check as close to game time as possible. Substitution profiles are not guaranteed as we depend on the site your team is on, Yahoo!, ESPN, CBS Sportsline, etc.. If these sites are experiencing slowness from load due to Sunday morning traffic, then it will also cause a delay in our service in getting over your substitution profiles. Also, we try to make sure that all substitution profiles have been completed before game time but if you have a player that is a game time decision and it's not on the official NFL wire before game time there is not anything we can do after the game starts.
We will look into the issue you are having with our mobile site and get that fixed ASAP.
If you have found issues outside of what you mention in this post, please let us know and we will address them ASAP. Send in support issues to support@screamingsports.com.
