1. Unclear, but this is the video about mistakes which happen because of quick show of hands https://youtube.com/watch?v=GiJ2IKomiFg (1.5 minutes short)
2. Because of a lot of votes. Can be many hundreds per day (for example, 300). This is good video https://youtube.com/watch?v=Ll6egB1AElk showing the voting process (short, but quite comprehensive for 1 minute)
3. I guess, because it is complex process. For example, vote FOR to reject a revote FOR child protection BUT AGAINST chat control, except all kinds of amendments proposed by parties swaying vote to either direction, like happened today, so even EPP who proposed a revote after accepted amendment voted against their own overall idea.
"whole voting process seems so confusing and user-hostile."
Usually they vote what the party tells them, so they copy the party position when voting, so it is a bit simpler just to copy others or what their party (group) decided.
Exception in 2nd video above where independent MEPs have to put more of their own work and prepare well before the vote.
