What happened?
While reviewing ID’d hyaena pics I’ve been running matching for some to confirm. Where this pulls in previously unassigned encounters that are a match for that ID’d individual, I’m clicking the checkbox to assign the target ID to the unassigned match result and I’m getting an error message: “Error updating encounter. Please enter a different Individual ID.” However refreshing the page shows that the action was completed correctly - the assignment shows for that match result. See screenshots below:


Hi, @ACWadmin1 !
I’m looping back through really old community posts that look like they slipped past us. Is this still an issue?
