Question in point: Does placing a lid on a pot affect the rate of boiling?.
I should have sufficient reputation to be allowed to answer - and I can, on the normal site. However when I view this question through the iOS app, the "answer" button does not appear for me - on two separate devices.
On other (unprotected) questions there is no problem. I don't recall noticing this behavior before...
And submitting this with just "iOS-app" and "bug-reports" tag generated an error. When I tried adding the "bug" tag and resubmitted I was told I could not submit my change for another 23 seconds. What gives?
