My refund was accepted Jan 27 and when I check my IRS app it says me refund is still being processed, no bar or anything. Is anyone else experiencing this? Should I worry?

This is normal. With the new tax laws and updates, the IRS is taking every precaution to ensure each tax return is process correctly and fully. There's no way to know when the IRS will update to refund approved. The best way to get an accurate direct deposit date is to continue checking the Where's My Refund tool on the IRS website. Updates are made daily, usually overnight. 

Since your return was accepted 21 days ago or more and you have not received an update via the Where's My Refund tool, you can follow the instructions in the following FAQ to contact the IRS for further assistance.
