@sotiri Hello again. I have since done two pilot on Prolific (each recruits ~20 subjects). One is the rating stories as I described above, the other is almost equivalent, just replacing stories with videos. Using 2020.2.5, I had no report of technical issue for the story task, which is great. However, for the video one, I got a bunch of problems (14 completed successfully, but several had issues).
(1) there was an issue with import condition file, as someone else has also encountered, it only happened to 1 of my subjects, and he uses a rather old version of Firefox (66). I was just wondering if you think it’s only an issue for older browsers?
(2) two of my subjects report the button click didn’t work, both using chrome 86 on Mac. I am not sure what’s the problem, there are subjects with the same setting that finish just fine.
(3) three subjects have memory related issues I believe, using chrome 86 on linux/ chrome 86 on windows/firefox 82 on windows (again, I have ones with the same settings that finish just fine). they describe it as video just went blank and failed to load/having a glitch. I set the log file to be ERROR because setting it to be DEBUG generates really big log files, but still, any ideas why?
