I know currently the timer to edit your jersey is disabled, but I've also spotted some comments that suggest it coming back eventually.
My suggestion is very small and simple. Could you leave it disabled? It's one of my favorite pastimes to tweak the shirt while waiting for the game simulation to complete. I've never quite understood the 30 days timer. If there's a valid reasoning behind having it, then just ignore this part of the post.
While on topic, is it possible to re-introduce the affiliate team editing without allocating too much valuable resources to it?
