Yes I did. This is what I learned:
Technically a US border agent could have detained for for not having proper documentation for entry (my conditional greencard was no longer valid as i am not a conditional resident anymore). They could have charged me $700 for not having the new 10 year greencard while still granting me you entry based on 10 year green card approval letter.
However in practice, in most cases, they just let you enter.
To improve my chances, I chose a friendly, smaller border crossing, and calked them in advance describing my situation and asked if they will allow me to enter with the old green card, extension letter and 10 year green card approval letter. I didn’t face any issues.
