Hi My extension is filed on 26 Dec 2019 to Texas service center. Any got Approval/RFE recently for extensions for Texas center
I am not sure about the Texas Center, but I do know that, if it was not in premium, many users are still waiting. This is quite normal. Talk to your employer and see, if they can raise a service request with USCIS, if it is beyond the processing time.
My H1B extension was files around same time and I got approval notice on April 14th. This was texas processing center as well.
