How were you notified about you I-131 approvals please? Email, mail, app, etc etc? I have been waiting 145 days for mine (filed 29 Dec 2017) and have already had to cancel two planned trips home to the UK as I do not have AP so can't leave without jeopardising my return. I've also put in 2 expedite requests and sent all the requested info immediately, but they never bothered to reply yes or no, despite confirming that that had received all the requested info. So incredibly frustrating!
