Hi Vinay,
I just checked it out and I realized that the problem is the label inside the form: if I enable it the privacy field disappear: https://ibb.co/5s5rnCV
I’m figuring out how to resolve it.

Just solved the issue.

I can solve in 3 ways:

1) My choice: add this lines into CSS: it will resize the title size on smartphone and prevent the problem.
@media only screen and (max-width: 480px)
{
h3.slide-entry-title.entry-title { font-size:20px!important; }
}

2) I don’t like so much the result but it works: split the 2 column into one on smartphone.
@media only screen and (max-width: 480px)
{
.flex_column { width: 100% !important; margin-left: 0 !important; }
}

3) This works also but it need to download twice the contents: open the screen option and check into the two column grid list “hide on very small screen”; then create another list using single author big img and check everything except “hide on very small screen”.
