Same here. Just received the text and I cannot check the status online yet. I am guessing it takes a while. Interestingly my bank account doesn't show the check has been cashed, but I am assuming if it wasn't I wouldn't had received the text with my case number. This is quite a relief and I intend to forget as much as possible about my case (except for making sure I carry the extension letter, going to biometrics, and looking out for RFEs), until I file N-400 next year. This was very stressful but it is nice to think that it could be the last time I have to submit so much evidence for an application!
