So Amazon sent me a replacement drone and it arrived today. The first thing I noticed is that the model is W322A whereas my older one is a W322B. Same deal with the RC: its is GL300B as opposed to GL300C for the older one (the older one P3A is only 3 weeks old) I tried to search but did not come up with any concrete evidence of a significant difference between the two. It would be great if someone could shed some light. In the meanwhile, I am also going to try and get in touch with DJI support. TIA!
