I must regularly reset my 7DII, it's nothing new. I'm sure canon thought it a good joke to play. Some do not believe until it is their turn. This camera is prone to things setting it off and a reset is the answer. I'm not one to constantly change setting because I know it will bite me in the you know what!! I leave the AF set to case 5 and about never change it. I use spot 99% of the time and centre group on birds in flight. I had big trouble with the back wheel and now the top wheel jumps to what ever it chooses, forward back ward not at all. It chooses and I live with it. Cant even bring myself to think about sending it in. Not really sure what to do about it but take 4 times longer to adjust on the fly. There is no setting maladjustment that will put the 7DII into a tail spin except making a change the shouldn't affect the outcome one gets. If you spend enough time with this camera you get to see the side of it I don't like..
