Enjoying the premium version of QSM but i did find few issues.
The Inline answers display wrong for even the correct answer.
One more thing is, once we have enabled the randomization of questions, the questions are randomized but while displaying the answers post submission it doesnt come in the same format as the questions were displayed instead it will be displayed in the order which was entered or saved in the database.
The issue occurs when the answers have empty blank spaces at the end. So please look for the blank spaces at the end of the answers and remove them.
And if you want to show Result of the random questions in the same way as they were displayed, then I will have to forward this as the feature request to the development team.
