Multiple Choice

Hi guys, 

First of all, I create an interaction in the H5P Interactive Video (i.e. a multiple choice quiz). 
Then, I save it. 

After few days, I return to my H5P Interactive Video and I want to edit the previous interaction, but...here begins the slow search. 

I have to move the video bar frame by frame in order to find the multiple choice interatcion. Sometimes, I can't find it also if I move very very slowly! Here is the question: 

Hi,

I've been using the Quiz options in H5P in my Moodle (v3.8) portal to create quizzes. However, I've found that whenever students complete their quizzes, they would have to close that browser window, in order to get back to the previous tabbed page. 

Is there a way to put a URL link at the end of the quiz, so students can "just click" to move forward to another topic/quiz or wherever I'd want them to move forward to? Although this is available in the Interactive Video option, where I can set a pop up window at the end of a video that allows URLs to be linked.

I'm having a problem with multiple-choice question types. The pages are slow to load and several of the ten multiple-choice messages on the page refuse to load and instead show an error message, as follows:
