I just logged into my AA account to discover that the Motley Fool 7400 miles has posted this week. This was unexpected, based on applying on 29th January, a day after the rules changed.The $99 credit has been appearing over the past several days. Certainly since 11th. The separate matter is the AA miles. Some will receive the miles, but it seems that others (including me) may not, based on the ordering date.
If I find the FT link about this, I will post it.
Edit: My guess is that I will not get the AA miles, due to (unknowingly) applying too late (on 29th)
So, for anyone who is in the same situation, it may be worth checking your AA account.
