Filed 3/22: Tax Return Still Processing After a Month - No Refund Date, No WMR Updates, Transcript Help Needed

Filed my taxes over a month ago on March 22nd and still showing no updates on WMR. I keep checking my transcripts but I have no idea what I'm looking at. No letters from the IRS either. Starting to get worried since everyone I know already got their refund. Anyone know what I should be looking for? I just checked the IRS website again and this is what I'm seeing: "Your tax return is still being processed. A refund date will be provided when available. For more information about processing delays, please see our Refund Frequently Asked Questions" It also shows my filing status as "Single" but doesn't show my expected refund amount anymore. The message says "Updates to refund status are made no more than once a day" but I've been checking for weeks with zero change. I've been using both the IRS website and the IRS2Go mobile app like they suggest, but getting the same message every time. The site mentions "Refund Frequently Asked Questions" but I've read through those and still don't understand why mine is taking so long when my tax situation isn't complicated. Has anyone else been stuck on "still being processed" for this long? Is there anything specific I should be looking for in my transcripts that might give me more information than the WMR tool? Should I try calling the IRS at this point, or just keep waiting?
