I upgraded to the iPhone 13 Sunday and had to re-setup my pairing with Mr. Powershot and forgot how to do it. I was playing with the settings when suddenly the camera would not turn on. I had to take the battery out and then re-insert to get the camera to work again. Perhaps a bug in the Canon software? I have tested the camera everyday since then and have not had a problem. I know I am out of warranty from Best Buy and I'd hate to have to replace Mr. Powershot with another Powershot so lets hope this was just a bug and not a hardware fault. Has anyone else had such a problem with either a Canon, Nikon, Sony, etc..?
