Thanks for the reply, I misspelled "emails" but you understood that I meant numbers, I'm attaching the requested images including one from my phone which recognizes them with the "+", for the filters I enabled the option to use "*"
I've blacklisted several emails with a "+" in front to identify them as foreign and block them, but the app doesn't always recognize it. It takes the number without the "+" and doesn't block it. The phone and another app correctly recognize that number with the "+."
