The missing copilot model is a known issue in the Warrrior II in MSFS 2024. We have developed a workaround for some of our other aircraft that will be implemented in the PA28s in the next update(s).
The main instrument panel lighting can be increased using the two rehostat switches on the main switch panel. All aircraft lighting may not be visible during to day due to a limitation of how MSFS 2024 handles aircraft lighting. The lighting in all of our MSFS 2024 aircraft has been fine-tuned to have a realistic brightness level at night, which does mean that certain lights can look dim or not lit during the day. If we were to increase the brightness of the lights to make them visible during the day, then that would have the side effect of making the lights extremely bright at night. We remain hopeful that this may be something that will be improved in future MSFS Sim Updates.
The EFB map flickering in MSFS 2024 was fixed in the v0.4.3 update to the Warrior II. Please ensure you have v0.4.3 of the Warrior II installed (version number can be seen at the top left corner of the EFB Aircraft page). If you are still experiencing this behaviour with v0.4.3, we kindly ask you to create a ticket with Just Flight Support via the following link, and one of our support team will be able to assist with further troubleshooting: https://www.justflight.com/support
