570 Code on Transcript with "Return Processing Delayed" Message - EITC PATH Hold or Different Issue?

Filed early January and my transcripts updated with a 570 code last week. Still showing N/A for the 846 code. I claimed EITC but can't figure out if I'm under PATH act review or if this is something else. Anyone know how to tell the difference? I just checked the IRS2Go app and I'm getting this message: "Return Received | Refund Approved | Refund Sent We apologize, but your return processing has been delayed beyond the normal timeframe. You can continue to check back here for the most up to date information regarding your refund. We understand your tax refund is very important and we are working to process your return as quickly as possible. Please read the following information related to your tax situation: Tax Topic 152, Refund Information 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 filed as Head of Household and claimed EITC. When I look at my transcripts I see the 570 code which I know means they're holding my refund for some reason, but there's still no 846 code (refund issued). Is this a PATH Act delay since I claimed EITC, or is something else going on? The app shows my return is received but then says processing is delayed. Does Tax Topic 152 mean I'm under review? How can I tell if this is just the normal PATH Act verification or if there's another issue with my return?
