Ok - but it would have been better to continue the original conversation, so that we know this suggestion has already been made (and didn't work).

You already asked this... https://moodle.org/mod/forum/discuss.php?d=462547

I'd never heard of 'picture in picture' in Moodle. Surely, this is a client/browser issue - not Moodle?

I had a quick look at the code for this call in question/bank/tagquestion/classes/external/submit_tags.php and that would appear to be the context id from the table you think it should be. I don't know why you're getting the exception. Maybe debugging up full?

It might just be me... but what bit of Moodle are we talking about?

You can, but you're going to have to battle with the - in my opinion - dreadful data privacy functions of Moodle.

Have fun - Data_privacy
