Spoof Filter Won’t Activate

I get anywhere from 25-50 spam calls per day, and I am at my wits’ end. I have the Premium version through my plan. When I log in, it says I have 2 of 3 filters activated. The third, which is the Neighbor Spoof Filter, will not turn on. I click the button to turn it on, and it spins nonstop and never finishes, no matter how long I wait. This is likely the feature that would be most useful to me, because every call I get is from a different number. I don’t have time to manually add 50 calls per day to my blocked list. The local US Cellular couldn’t help me. I guess I’m just with this reality. I’m glad I’m not actually paying for the Premium version, though I’m sure the charge is buried somewhere in my plan fees.

Useless, unless updates are made.

Through my U.S. Cellular plan, I am supposed to be able to access the premium plan on Call Guardian for free. But I have repeatedly tried to access it and it continually sends me verification codes to verify my number and then gives me a pop-up that says “Unable to complete action: your account is not authorized to complete this purchase. Please call 611 for assistance and try again” with an “OK” button, while in the background there is a screen that is blue and says “All Done, Congrats! Call Guardian Premium is included with your rate plan and has now been activated in your device”. Once I hit “OK” to the pop-up, it brings me immediately back to the phone number verification screen. I have had Call Guardian installed for a few months now and was excited for such software to exist to put a stop to the literal NON-STOP calls I get from spammers, spoofers, and robo-calls on a daily freaking basis. I have to literally tell people who I want to call me that if I don’t answer, to please, PLEASE, PLEASE leave a voicemail, because otherwise I will just assume their number is spam/spoofed.

New Spam numbers never download

I use the Basic version and keep getting messages that new there are updates to the list of spam numbers that need to be downloaded but when I attempt to do so I just get the spinning download indicator amd nothing ever indicates anything was downloaded. There is nothing indicating that this is a Premium-only feature so I can only assume the app is defective. US Cellular should really consider an alternative.
