Bring back headerless iOS app! Header is present after automatic app update

Hello,

Title says it all. I think that sometime this week an automatic iOS app update was deployed, which erased the no-header, or better to call transparent header option. Prior to the update, it was possible to make the header transparent and enjoy a true top to bottom full screen experience when selecting something like “developer mode” or “beta mode” in app settings.
Can we have transparent header back? Please?

Adding pictures of transparent vs opaque header.
(Color of opaque header is modified to match background as much as possible, but still not a true full screen experience)
