Impact on H1-B and H4 after getting EAD from approved I485

[varajput]

I am on H1-B visa and my wife is on H4 Visa, stamped in our passport, validity till Jan 2026.

We got our EAD after our I485 approval. I am using my H1-B visa for my Job and My wife started working after getting EAD and using EAD(from I485) for job.

Does it mean.

1. She lost her H4 visa and now she will only be able to enter US (if we go outside US)using her Advance Parol?
2. Does it mean I also lost my H1-B and have to use Advance Parol to enter US(if we go outside US).
3. If answer for 2nd question is yes then does it mean I have to give EAD to my employer and asking them to use it for employment purpose.
