How can I see which team members’ approval transfers are pending review?

Only if you have the "Owner" or "Admin" role:

Step 1: Go to Venn "Transactions"

Step 2: Select the section "Needs Approval"

This will show all transfers that are pending review which needs to be either approved or rejected.

Alternatively, you may also ask the team member who initiated the transfer to go to Venn "Tasks" and share a screenshot of what are outstanding tasks pending on their end.
