Hi @Toddler68 and welcome to the forums!
Please first read the information for:
- Memory Logging in the Sim Update 3 Beta
- Changes to Career/Challenge League in the Sim Update 3 Beta
- What to Know Before You Join
- Update to the Microsoft Flight Simulator 2024 Insider Program
in this post:
Since you are on steam, you can disregard the sign-up instructions for MS-Store users.
I’m not on Steam, so cannot guarantee this is 100% accurate, but for Steam users the instructions are (I think) the same as for the Beta 2 build, as outlined in this post
STEAM
- Open your Steam Library
- Right-click Microsoft Flight Simulator 2024
- Click “Properties”
- Click “Betas”
- Select “flight_sim_beta – Sim Update 2"
[Edit: Despite saying “Sim Update 2” it will enroll you in Sim Update 3, as kindly confirmed by @DeePreed and @TheShavenWookie a few posts further on in this topic.]
