## Summary After a silent reboot, there was a small window where the esp32 would listen for button presses but the full refresh would hold the event loop. This gave a UX experience where the silent reboot had completed to the home screen, a user taps select (at any time during the process), and they find themselves unexpectedly in a book. ## Additional Context This must land after https://github.com/crosspoint-reader/community-sdk/pull/11 and will need the submodule SHA changes included in. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.
