just tried to do my ds this morning on antacids where i had to watch videos and give my opinions on them. spent almost 30 minutes on it (went very very slowly) and on a plain blank white page i got the following message:

Thank you for sharing your opinions!
Thanks a lot. Unfortunately, you do not qualify for this particular survey.





PLEASE NOTE: Only one submission per person is accepted.
reported this to gf as i spent a lot of time on it. just wanted to give everyone the heads up about this survey.
