Hello,
We have 2 different Surveys and we are seen this behavior.
When we open the fist survey in the browser we have the situation with some questions from our survey using the question type select one within a group. When selecting one of the options, only the option is shaded but the dot is not visible checked.

In this other survey, using the table list appearance when the survey is opened from a cell phone the options does not fit the iphone 11 screen.

So, your question is, are these bugs or expected behavior.
Thanks for your help!
