H1 Transfer query

My original petition validity got reduced based on new amendment SOW from march 2020 to march 2019.

This result I received in Feb 2019, before that I applied for H1 transfer in Jan 2019. Where I had submitted my old original H1b Visa approval till march 2020 validity.

Question is, is this recent changes may impact on in progress H1 transfer petition. Should I inform my attorney to send latest approved visa (march 2019)??

I94 got also updated based on new updates as 31st march 2019.

Please suggest.

Yes, you should inform them because there could be an RFE, if the details do not match. It is always good to keep your attorney informed as they can plan on how to address it.
