Formula to insert text based on date

[Flora2021]

Hi, I have a ongoing weekly report where I have to add reason codes based on a few factors.
What I have been doing is using a VLOOKUP based on a status (column g) to return the matching value from another sheet and insert into Column U. This part is working fine. However what I am still having to do manually is in column M, if that date is 3 days in the past from today, I have to manually in a reason code (in column U) This would say No Movement in 3+ days.
Any ideas what kind of a formula I can use? Thanks in advance

I was able to half way get this working by using:
=IF((NOW()-M2)>3, "Yes", "No") but I want the value returned to say No Movement in 3+ days if it should be yes, and blank if no. I think I am close though.

Didn't fully understand the problem (without actual data), but what stops you to write it right this text in the formula?

Perhaps

=IF(TODAY()-M2>3,"No Movement","")
