Thanks for the reply. Yes I've been doing the same thing. I logged into my account first and adding the products. It's starting to look like it's my account that's the problem. I will call them again to see if they can fix it. I'm also surprised that they can't register my camera over the phone!
That's pretty odd and I hope they check into it to see if your account is to blame. I recall in the later half of last year (2020) Canon was having problems, but surely they have it squared away by now. The fact that you and another in this thread has the same issue indicates that something is going on. You may have to resort to the mail in reg. that came with your device. I would also check that the vendor you bought your device from is certified by Canon. I've read that Canon USA will reject some serial numbers, depending on who/where the items were sold, Gray Market comes to mind, but I have no first hand experience with that 🙂
Thanks. I bought my R6 from Amazon (sold by Amazon itself) and EF to R adapter from Canon USA store. So I'm pretty sure it's not the serial number issue. I'm planning on calling again tomorrow to find out if they could reach out to their IT person.
Great! That eliminates that as a reason. I bought the same thing, the R6 and adapter, LOL! I'm enjoying the heck out of it so far.
