Hello,
I have added randomizer with a few blocks on the survey. I previewed the survey a few time and to see it randomizes. I noticed that the blocks it do not seem to randomize. 
Randomizer does not work with preview?
+38How many times have you tested? You might need several tries to see the order flip.
Perhaps a better way to generate test data and check the data file for block order.
If you are wanting it to choose a block to show then you need to change the number from 2 to 1 in your randomizer and check Evenly Present Elements.
