Can't block spam numbers
Hi, I have a spam problem that I can't solve by adding spam numbers to the blacklist. When I try to add a number to the blacklist (by clicking the number and then the info icon), it shows me that the number was successfully added to the blacklist, but when I close the info panel (with the ready button), the number gets unblocked, what can be discovered by entering the info panel once again. How can I block them? I had found nothing on Google, seems like this blocking function works properly on every device, except mine.
Thanks for help.
