I agree, I did see something like that. However, there is a take a break icon. When pressed, it says you must review all answers and submit as you can't go back and they will be "locked". So, after doing that, I received a screen that said break in progress, all previous answers locked, etc. The screen was basically blank with the "break in progress" or whatever terminology in the middle, no questions or answers available. There was a "resume exam (or test, can't remember)" button. I clicked that upon return, and all previous answers were locked. Then it went to question 93, and 10 seconds in I was notified about the termination. My assumption (and critical mistake it appears) was that the proctor was notified with this process and that they placed the exam on hold. Doing this, then having to message the proctor and wait during exam time is redundant, and the screen should have said "please wait for your proctor to approve your break" or something in red, or whatever. You should either be able to click the break button or be required to message the proctor and they then place the test on hold. The test being placed on hold, making it appear like it is ok but not having the proctor's blessing to leave the room is misleading at best. I more or less messed up, but I do want to let people know it can be very misleading when in a stressful environment (test). Sorry to vent. Good luck to everyone still testing.
Also, for the record, I took Sections 1 and 2 from home in Dec 2020 and was able to take a break each time, and this was not an issue. It was a good experience. It was simple and clear. So far PSI seems terrible and I personally would have rather pearson vue do online for secs 3 & 4, but whatever.
