IRS Transcript Changed From "Still Being Processed" to "Received and Being Processed" - Stuck at First Stage of Refund Status

Filed my taxes last year and my transcript status changed from 'still being processed' to "We have received your tax return and it is being processed." Not sure what this means or if its good news. Anyone else experience this type of change? I really need this money and tired of checking WMR every day. I was checking the IRS2Go app again today at 2:11 and saw that my refund status is showing three stages: "Refund Received," "Refund Approved," and "Refund Sent" - but I'm still stuck at the first stage. The message says "We have received your tax return and it is being processed. Please Note: For refund information, please continue to check here, or visit IRS.gov/Refunds. Updates to refund status are made no more than once a day." I've been checking this app constantly, looking at the "Refunds" and "Payments" tabs hoping for some movement. I filed Single status and I'm expecting a substantial refund that I really need right now. Has anyone had their status change from this processing message to approval? How long did it take? The waiting and constant checking is driving me crazy.
