TEAMMATES
Answering rubric questions: only one row can be clicked
v8.14.1
Two users (I remember at least one more case reported sometime back) have reported that when answering a rubric question, an option from only one row can be clicked. Upon clicking another row, the previously clicked row is reset.
Example:
At the bottom of the page, where we are supposed to choose 1 response in all 5 categories for each member, it will only allow me to choose 1 response out of all 5 categories for each member. So I'm only able to mark 1 evaluation per teammate, out of all 20 options.
Example:
For question 7: team ratings, I cannot select multiple lines. Each time that I select a response on a line it deletes the response that it precedes it.
The second user managed to submit eventually.
Co-incidentally, I found this error in the logs related to rubric questions, reported a whole bunch of times during the last month, may or may not be linked though.

Vast majority of students in the same session (of 118 students) as the above two submitted that question without any problem though, based on session results.
Also, if "the [second] user managed to submit eventually", high chance that the first problem is also stale front-end cache.
