@KiltedTim why be so hostile towards OP? This is a very valid question/concern to have.
For anyone wondering, this is a bug. Apple apps have a key/placeholder value for buttons for devs to toggle on. This looks like they forgot to turn off the feature flag in a production app and that’s why we’re seeing a button that isn’t mapped to a function and doesn’t have proper button text presented.
I also have this but I’m currently running iOS beta and I’ve previously seen this in a few places within settings running beta.
This should be fixed in the next update.
