For some reason for our case we haven't received any texts or emails so we assume somehow they lost our sheet that had that information; but I checked the case status on uscis and thats the most important thing (: Once you see the update to 'my case has been approved' they will then send you a letter which you will receive some time after. So, for now I would say focus on checking the case status!
