Have you tried on you Meta Business Account?

I think what the guy meant to ask is where   in Facebook is the action of changing the image performed. I agree with his question Thanks

I guess you can go into your WhatsApp / Meta Business Manager (https://business.facebook.com/wa/manage/home/) , hover over Account Tools in the left menu, then select “Phone Numbers”. On the next screen you’ll see a list of your phone numbers. Click the gear icon and navigate to the Profile tab. From there you can edit your profile picture for your WhatsApp business profile.

😀Thank you very much😀

Hello there, it happens to me, i found the solution, just by adjustment the size of the profile picture to 640px / 640px max size. Hope its work for you man.
