Zoom background always blurred

[MP241]

I am using Samsung/Android and just today noticed I can't remove the blur from my Zoom background.  I have tested on different Zoom accounts and the "blur" is on all of them.    It is not quite as blurred as the "Blur" option in the "Background & Effects" but clearly out of focus even thoughts I tap "none" .

This seriously affects my work so would urgently need help.
Has anyone seen this behavior or know how to correct it?
