If the update of the spam protection fails, the iPhone setting “Call Blocking & Identification”, which is absolutely necessary for spam detection, was deactivated in the background. This may have been triggered by an iOS update, for example. The reason is the security structure of the iPhone, which is why we unfortunately cannot influence this problem. All other iOS apps that require this setting struggle with this problem.
Please check in the app Settings >> Phone >> Call Blocking & Identification whether the Clever Dialer app can be easily reactivated here. (see description)
Possibly, the switch that must be activated for Clever Dialer to work, is showing a loading icon and therefore cannot be activated.
Please follow these steps to solve the problem:
– Switch off your iPhone (Settings >> General >> Switch off)
– Wait 5 minutes, better 15 minutes, before you turn it on again
– Reinstall the Clever Dialer App
