Oh well, ISY now won't block texts from 24719 anymore, either. So, I've just attempted to set up a Youmail account. Wow. I'm reluctant to give out an email address, so I set one up on the anonymous Protonmail. So far so good. Put in a fake name. Then the setup began displaying & dialing 3 or 4 completely random numbers for a reasons I do not get. WTF??? I just want something which will ALWAYS COMPLETELY BLOCK any number I tell it to. WHY does this App need "an account", and what is the point of those random numbers? I have deleted Youmail since I have no idea what it's doing with all this. I don't need to have blocked calls "forwarded", just BLOCKED and sent to oblivion. What am I missing here? Open to retrying Youmail given the recommendations, but what is all this about? TIA
