You may want to sign up at our Feedback Community to get further information on getting involved in future beta testing! Let me know if you have further questions. Thanks!
The site is the same but on the left side there click on the "About Me" tab and then under "Preferences" you should be able to select the product that you would like to be a beta tester for. Have you selected that option?
Not everyone is invited into every beta project and this decision is up to each product team and their ability to support participants. Teams may also try to prioritize past product beta participants that were active participants and will at times only re-invite those that were actively providing feedback during the past beta and not just getting the software but not actively providing any feedback.
