V2 has lots of reliance on google services to determine if it thinks you are a bot, and maybe jumps to check these boxes for us too quick, v3 as I understand is based on human heuristics to determine the percentile chance someone is a bot and you catch that chance in your code and decide what you want to do based on it.
