Its been like that for me since I ordered the device. Got the text with a CONFIRMATION and order #. Got an email as well, along with the estimated ship date (Sep 19-26). The app shows the order as 'being processed' but in my-tmobile it does not show up, and I cannot look it up using the order # and lookup link provided in the email. I've reached out to them and they said that I need not worry and that the order stands conformed and is being processed.
Thanks. I am on hold with them and will let you know if I get the same response.
