We just created ten tests with Storyline. We have noticed strange behaviors with some of them.
Many final results are not recorded in Articulate-Online while some are for the same quiz.
On one test, I completed it numerous times on my PC and each time I was opening it after, I was sent back to the same place I stopped once, nothing having been recorded in Articulate-Online. Then, I dit it on my Mac without problems. Some other tests I did on my PC have beed recorded just fine. The PC browser we recommend is Google Chrome (V. 47 or later.)
