Moodle site 3.6.2 and error is in quiz on custom mobile apps (upto 3.4.0 versions).
I changed user defined roles 1-2 months back when i move to another server. I also upgraded the site to 3.6.2 . It is due to a setting in the website or server.
I'm not sure when the error started.
Now, I see that when i open a quiz, the button 'Attempt Quiz' does not show, I see a button 'Continue previous attempt'.
I select a multiple choice answer and click Next.
I get the error popup 'Cannot read property 'finished' of undefined'
Quiz answers do not get saved.
The quiz is okay in a browser.
What may be the cause? -> Role settings for Authenticated User and Student?
Or Redirects when i moved the site to a new server?
