What Wildbook are you working in?
Flukebook

What is the entire URL out of the browser, exactly where the error occurred?
URL of match results page:

URL of encounter:

URL of individual:

Included a screenshot of the error message below

Can you describe what the issue is you’re experiencing?
unable to submit a potential match, “user unauthorised”

Can you provide steps on how to reproduce what you’re experiencing?
When reviewing potential matches, I am unable to proceed past ticking the checkbox. Once the checkbox is ticked, I get a “use individual xxxx for unnamed match below” banner, when i click it I get “user unauthorised for encounter”. I am unable to request collaboration with the other submitter as no link appears behind the individual scores.

Edit: this happened again with another match:

Again a user that I am unable to request to collaborate with.

Hi @liv

Great match!

It looks like the matched Encounter:

is owned by Bianca Tree. To make their unassigned Encounter a marked individual with yours, you would need to have a collaboration in place in Flukebook with Bianca. Do you know this individual and/or do you know how to request collaboration from the Flukebook user interface via the Collaborations section on your account page?

There is more information about our silo security system here:

Please let me know if you need help getting the collaboration request out or don’t get a response soon.

Thank you,
Jason
