Filers who mailed paper returns in April 2025 - has anyone received their return-receipt or refund yet?

Has anyone who mailed a paper return in April received their refund or return-receipt back yet? Or at least seen the tracking indicate the receipt is on the way back? It is almost June and the agency website seems to indicate they haven't even begun processing paper returns received in April.

 

Am wondering what others are experiencing...
