I have updated to 19.04. from 18.04 LTS (first to 18.10 then 19.04)
I used to have a question mark in my WIFI sign at the right corner with 18.04. I turned connectivity checking off in privacy settings and it disappeared.
Now the question mark is there again with 19.04 and i have to turn on and off connectivity checking whenever i log in.
any ideas?
