When trying to complete this portion of training, each of the 16 “blocks” will have a check-mark on each when that block’s training is completed. However, the Blocks move to the right of the screen and then disappear. I tried 3 different browsers (Firefox, MS Chrome & MS Edge) and had the same problem. I’ve spent 1.5 hrs trying to get through this training video. I was able to “game” the disappearing blocks by starting in the upper right corner and down that column, so I was able to complete all 16 blocks, however I still was not able to advance past this screen (must be a “continue” box to hit, which I can’t see.
See pic uploaded to see the “after” view of completed training and how 8 blocks disappeared. Thanks for your time and assistance.
