For any content you purchased outside of the simulator, the Community Folder will continue to work as it did in MSFS 2020. Any content in your MSFS 2020 Community Folder can simply be copied over to the new MSFS 2024 Community Folder, and the vast majority of that content should work in MSFS 2024. For any content you purchased in the Marketplace in MSFS 2020, that content will show up as owned in the Content Manager (in MSFS 2024 called “My Library”) at launch for you to use in MSFS 2024, and the vast majority of that content should work in MSFS 2024. This availability does not require developers to sign off on their content.
Step 1: Get tested for sleep apnea. If you have it, snoring is the least of your worries. Don’t skip this step.
Otherwise, sleep on your side, elevate your upper body (Amazon sells wedge pillows).
If you are certain you don’t have apnea, you can also try a chin strap. Just be sure any chin strap you buy pulls your chin up, not back, as this will A: Obstruct breathing, and B: cause major jaw pain.
