I have a Moto G7 play (2 mos old) with Android 9 installed (not beta). Call Screen works fine for a day or two, then disappears. Meaning, I get tons of spam calls and the Screen option is available and I can use it, then it is not available as an option for a day or two and then its back again. In addition, the Call Screen option is not available in Settings (although Caller Id & spam is there). I have tried updating the Phone app, restarts and they don’t affect it.
