In Verizon Call Filter with my iPhone SE (17.3.1), I press "Get started". It grinds and grinds, and displays "checking account status". Finally it comes back with "We couldn't authenticate your device". This has been happening for weeks. What's the problem? My phone works perfectly otherwise. I see this issue asked about a lot, and no solutions are ever posted. I believe my Call Filter is actually working, though, because spam is identified.
