Really late refund

My 2021 tax return was accepted 2/2/22

I filed electronically so I received a letter asking for documents on 3/4/22.  Sent same day.

Documents were received by IRS 3/14/22

4/22/22 - No refund yet

Called the IRS advocate on 4/22/22.  The lady said they're not even talking to people about their 2021 returns yet.  WTF?  A friend called them and they were very helpful with his 2021 return question.
