Ever since I started using this NFC brick, things have been going great, but I've recently run into a new loophole. I can still access my distracting apps without having to use the emergency unbrick or tap my NFC brick.
Instead, I can just go into the Settings app, scroll down to Screen Time, and toggle off the main switch, which instantly unblocks all distracted apps. While I thought about using the Shortcuts app to automate a workaround for this, unfortunately, that method doesn't work either.
