"Bundle cannot have recipients who share the same email" when sending FuseSign document bundle

Issue
When sending a document bundle to FuseSign to 2 recipients with the same email but different phone numbers in contacts, the following error is displayed:

"Bundle cannot have recipients who share the same email"

This has been escalated to engineering.

Workaround
Add the additional signer manually to the documents within FuseSign until the fix is released.
