Job change when AC21 Filed, No Acknowledgement, AOS approved

[vac21]

I had my AOS pending for 2 years.  I decided to change jobs a couple of months back, filed AC21 (assuming here that it was filed by the lawyer).  I have not received any acknowledgement from USCIS.  The USCIS online tool updated my case status recently stating that a decision notice had been mailed to me.  It also states that they had registered my PR Status and follow up instructions will be in the notice.

 

I have not changed employers yet.  At this point I don't know if I should.  Will it impact me negatively if I do (because I am shifting jobs right after I485 case status change without AC21 acknowledgement)?  Will it negatively impact me if I don't (because I have filed AC21.  I am not sure if USCIS received it.).  At this point, I am fine working for either employers as long as my green card status is unaffected. My only concern/aim is that my green card is intact.

 

Please write your recommendations on what I should do?

 . I called murthy lawyers for my GC. They mentioned its not mandatory  for USCIS to acknowledge your AC21 . So even if they get it some times they will notify you that they received sometimes wont.
