Blocked app exemption does not count time spent in app

On a blocked “brainrot” app, users can request usage time (e.g. instagram). Assume I request 5mins for instagram to post a story. The app starts an absolute time countdown instead of counting 5 minutes actually spent in the app. If I need to check my gallery first, do some research or check another app in the meantime, the time runs out and I need to resubmit a humiliating request, even though I really just needed 5mins to post a story.
