On step 41 through 47, my addTrack method in Apps.Js is not correctly initialized. This further caused issue as I added removeTrack and so forth. I tried backtracking all of the objects that I established and combed through everything but still couldn’t get it to define. I looked into the REACT dev extension tool and the error I get is that “this.setState” is not a function as well.
I followed the video step by step to double check and couldn’t find anything differ.
I’ve attached photos for reference.
Thanks for your help!
