The Minecraft Modding 1 video is stuck on the final concept. When the video goes to break the blocks, it breaks the first glass block and then refuses to progress to breaking the other 2 blocks, therefore you can not progress. For something we paid for, I’d expect it to work. My child had gotten super interested in the videos and was excited to work through it and now he is frustrated because he can’t complete the lesson.
We tried three different browsers, Chrome, Edge and Firefox. None of them would progress past the block breaking.
