Hey All: I am attempting to create Access Tokens in the Sandbox for a client of mine. However, my user (with administrator role assigned and Access Token Management privilege assigned) isn't showing in the user list. I also cannot reset the credentials in the integration record itself. Has anyone else seen this behavior, or have any suggestions for troubleshooting?

Yeah if you go through setup user etc etc you don't get offered Admin as a role. If you navigate, as you found, to your home page as a logged on Admin you can do it that way. Not sure if it's a loophole NS haven't noticed / plugged but I believe they discourage the use of an admin role generally.
