When you send an email via a workflow with managed metadata items they look like TERM1|ifdijfigjdiojgikdjfgidjgildjlgk.
I have tried with the new Microsoft flow and it does exactly the same (before I tried with SharePoint designer workflows).
Is there a way to clean up the code portion in order to show just the Term either in SPD Workflow or Flow? By chance is it exactly the same process? (additional 2 columns with copy=paste and removal of the extra letters with a formula?)
