Ubuntu Server 18.04 Minimal
Cannot create a "segment" of visitors on Matomo dashboard, restricted to United States visitors, by "Country"
Trying "United" for "United States" or "United States of America"
Trying abbreviated form "US" for "US" or "USA"
Using the country code US
Because a workaround is possible and this is not security related, I do not believe this is a high priority bug. However, I do want to document both the bug and the temporary solution for other end-users.
