Yesterday i face a weird issue while importing a data file to my tenant. I was using UI to import my users file and what happened is that some users were already in my tenant, and upsert fileds was set to default (false) but still my already existing users gets updated with new. This was strange behavior. Can you help me here.
Are you able to reproduce this? Can you provide reproduction steps?
I will get back to you on this soon if this happened again.
