My .02:

• From a psychological standpoint, when a meeting goes backwards instead of forwards, it feels bad. Speaking for myself, whenever the person leading a meeting says "let's go back and redo..." I disengage. The root cause here is that the facilitator moved forward before the team was ready. Preventing them from making a mistake is always preferable to allowing them to undo the mistake!
• Why does the facilitator move forward before everybody is ready? If everyone else hasn't clicked the "Ready" button, then when the facilitator clicks "next" they get a tooltip and have to click "next" again to move forward. This is the area that's broken! Is the tooltip unclear? How could we make the words more meaningful? Do we say "Is everyone ready? If so click next again". Should we specify that if they move forward they can't move back? Do they know that the team can still add reflections in the group phase?
