Help Call Blockers not working on Pie

[loonee2n]

Before my phone upgraded to Pie, I had a call blocker that worked perfect on Oreo. If you weren't in my contacts you were sent to voicemail and I didn't know you called. After the upgrade, I started getting phone calls from unknown numbers, so I figured the app wasn't compatible. I installed multiple other call blocking apps, but none of them kept my phone from ringing from numbers that they were supposed to block. I even tried the Do Not Disturb trick, but the calls came through on DND also.

Is anyone else having this problem, or has there been a suggestion of what to do? I'm asking before I get frustrated enough to root the phone and flash back to an Oreo ROM.

Youmail is a call blocking app that may help

Youmail doesn't work well with prepaid plans. They even mention it in the app description. Verizon doesn't even give me access to their new call blocking and visual voicemail apps on the prepaid plan. Plus I don't like the registering process. The apps that worked perfect on Oreo were install and forget. Thank you for the recommendation though.
