h1-b extension shows post decision and no letter until now and nothing it says of approval of any thing else

my case status is showing post decision and there is nothing written for approval or not . We filed a extension for h1b after I-140 got approved. H4 is still showing initial review and h1 is post- decision. Does anyone know how does it work . We have a reciept notice for sep2 and sep22 is post decision.

Please help

I would guess that this is an approval. Timeline hints at a positive decision. Please keep us informed.
