Hi, sprintership!

So that the Community can help you better, we need to know exactly which operating system is running on your mobile device (i.e. Android or iOS, and which version thereof).  If you're using multiple devices, please provide that information for each one. That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, click HERE search our knowledge base or find additional support options HERE.

Thanks and have a great day!

Of course, the problem started right after updating CANON firmware not my iPhone firmware.


IPHONE software 15.1 and Canon whatever is the latest one. I did update yesterday and right after the update a lot of employees reported the same problem.
