About: Your streamtag name has to be unique across the whole Live Video Cloud platform, even teams you don't have access to. This is why you might see a message "Streamtag with this name already exists." when trying to create your streamtag, alerting you that the name you chose is already taken and you have to choose a different one.

Streamtag with this name already exists

You can try the following to make your streamtag name unique:
Add your team, production or show name
For example:
#dayevent5-ingest
instead of
#ingest
Or for example:
#team-5pmshowpgm
instead of
#pgm
Add date or time information
For example:
#20220120-iso1
instead of
#iso1
