Update: I found where the redirect is happening. It’s at line 87 and 89 of ultimate-member/core/um-actions-wpadmin.php. For those who really need OAuth to work with UM you can add this inside the if statement at line 84: && $_REQUEST['action'] != 'oauth1_authorize' and it should work.

I currently have the same problem. When trying to authorize with the /oauth1/authorize endpoint I always get redirected to wp-admin.
I suspect UM to do some kind of redirection when the OAuth plugin tries to open wp-login to ask for authorization even though the backend login screen and backend register screen are enabled in the “Access” tab of UM.
