I'm in a bit of a pickle. Back in December we had an old developer start to work on the RingCentral integration with our software that we are developing. He is no longer with the company, but we are now starting to work on integrating RingCentral again. I have created a totally new app, but I seem to have no ability to remove the original developer's user account, and, more importantly, it's using the same sandbox credentials and says it wants to reset the password and send it to his email.
I want to try and remove his account from the equation totally if possible and kind of start fresh with new sandbox credentials and everything, but I can't figure out how to go about doing that. I am the SuperAdmin for our RingCentral account but can't do much of anything. Any help I could get with this would be much appreciated!
