After you file

Not helpful.   I can't get an answer anywhere.  Links to information keep saying there are 3  stages of my refund: recieved, approved, sent.  My says still processing and has been in that stage for more than 2 weeks. My refund was not complicated.  And now the website for irs.gov says it is down for maintenance. And now when I go to IRSGo on my phone app it says "error " and that my information does not match. My information regarding my ss #, filing status, and amount has not changed since i filed.
