I have a Zenfone ZE520kl with the last version of Secure Antivirus free installed on it.
Till a few days ago I had Nougat 7.0 on it and the SMS and calls block function worked like a charm.
Then I updated it on Oreo (version 8.0).
Last day I received an SMS from a blocked number.
The antivirus alerted me that an unwanted SMS was sent to me from a blocked sender but the SMS was there, together with the other not-blocked ones.
In the past I only received the warning from Webroot , the SMS was not delivered to me.
While it can seem a "no biggie" for SMS (also if it should need to be brought back to the old behaviour) I'm wondering about the calls.......
what if a blocked sender calls me? If the calls block doesn't work in the same way the SMS one, that can be a problem.
Thanks in advance for your help

Some versions of Android (particularly newer OS versions) do not allow 3rd party apps like ours to remove SMS messages after they are received. That would explain the change in behavior after the OS update.
We have not seen any similar limitation with call blocking, which sounds like your main concern.
I hope that helps!
