Cannot go back to stable Android 10 from Android 11 Beta. Why?

[Android Central Question]

Trying to Opt out of Android 11 Beta. Every time I attempt to download Android 10 OTA one of two things happens: Either the "Optimizing Apps" progress bar will stop just before finishing and actually regress backwards; or when I do the factory data reset, I end up with Android 11 Beta anyways.
-Pixel 4 64 gb
-Verizon Wireless
-RCS Chat ALSO not working
- I have confirmed that I can see an "Opt In" on the Android Beta page meaning I have successfully opted out.

RCS Chat features finally working after weeks without it. After countless bug reports, Google said they fixed the issue and would push an update. Not entirely sure what the update was to: Android Messages app; Carrier Services; etc but it works now.

Glad to hear that
