Can't access Halo Waypoint beta app! Help!

Alright, I’m gonna give this one last try as my topic gets blasted into oblivion within 2 minutes. I’m on Android (Galaxy Note 9, Android 10). I have tried everything to get the “Join Beta” to show up, and nothing works. Cleared Google Play cache, restart the phone, double-checked everything was updated and my Insider settings were correct, made sure my Waypoint/Microsoft account had the same email as my Google account, uninstalled, reinstalled, anything I could do. This damn beta just won’t show up for me. I had the same problem during the first tech preview. I’ve submitted a ticket and I’m awaiting a response (other than the auto-response I received) as the link they gave me to download the beta is giving me an “Access Denied” message. I’m at my wits end with this lol. Anyone else having the same problem/know what to do?

While the apps were part of the first flight, they are not a focus and not available for this one.
