k12.instructure.com vs. canvas.instructure.com Issues

[HumanJHawkins]

In my school, one teacher created a free account under canvas.instructure.com. Another (me) under k12.instructure.com. Students have randomly landed in each of these two places depending on whose class they had first.

In theory, this can work because the system tries to sort it out for the user. In practice, it doesn't work. It's very fragile. And troubleshooting is a nightmare. Students randomly lose access. Attempts to change passwords fail and lock students out without a working reset process.

I'd like to get everyone who is not on canvas.instructure.com onto it. (This is only about 15 students and 1 teacher I think.) Ideally, we could delete/remove all remnants of k12.instructure.com from these user accounts, such that we would get an error message if someone tried to use k12.

Is this possible? How can one go about getting all students onto the same one-and-only system?

Thanks.

Hi, please check your private messages, I can try and assist you.

@KevinMeredith Hi Kevin, You helped me about three weeks ago with two students. One of those students is just now available to actually implement your suggestions. I attempted to get back to the private messages to confirm username/login details, etc. But those messages have disappeared.

I don't see any way to either send you a private message, nor access the prior messages you have sent (even the notifications have disappeared, though I do have notifications for a different post subscription from weeks before you helped me.)

If you are able, please send a new PM... That might allow me to see the others. Or if you have access to that conversation, it would be a big help if you would send it again.

Thanks.
