Why are so many of my AI images getting rejected lately?

I never faced any problems with my interior design images until a couple of weeks ago. 

Since then almost all of them get rejected for quality reasons and I do not understand why.

Do you have any idea??

What I notice are rendering errors. Round objects look squished and oval shaped.

AI images without transparent backgrounds should be jpg's, not png's.

Correct. But Adobe does not care, they convert silently to JPEG.

Well, they seem then to check the assets more stringently, because I see many issues, and each of those should earn you a refusal. And I didn't even do an indepth check.

AI mistakes & drawing issues aside, these all seem rather dark & drab.  They could benefit from some Levels adjustment.
