Untagging your invitees can be done in your Invite List, manually or in bulk.
To manually untag invitee(s), click on the invitee you want to untag, locate the tag and click on the 'x' icon next to the tag. Click Save when you are done.
To untag more invitees at once, tick the boxes next to their names (to untag all invitees tick the box on the left of the 'Title' column), click on the 'Actions' button and then select 'Untag'. Choose which tags you want to remove and then click 'Untag Invitees'. Your invitees will be untagged after this.
Step 1: Tick the box next to the 'Title' column
This will automatically select all invitees on the current page. If you would like to select all, choose the "select all rows" option
Just like tagging, the untagging can be done from the Dashboard > Overview as well, manually and in bulk.
Manually means to open up the submission, locate the tag and click on the 'x' next to it. Untagging in bulk would mean selecting a few/all submissions, click on the 'Actions' button and then select 'Untag'. To remove tags you would need to choose which ones you want to remove and then click 'Untag Invitees'.
