Came here with the solution! Thanks for your help, @dbrace and @melodyc_lam
In my Canvas instance, it clearly showed that I was made the full admin and coworker as the sub account admin. However, the CTO of our organization said that the change needed to be made on THEIR end and not on our end. So it reflected the changes were made, but they were not accurate. The CTO had to change it on their end, and now I am an actual full admin.
So, moral of the story, don't believe what you see if you are part of an organization that has an MOU/Deal with Canvas. You will likely need help from a higher up.
