When adding Inclusion or exclusion LinkedIn Native Audiences you may run into the following error:
This limit is enforced directly by LinkedIn, if you try to add over 200 countries natively the same error will be encountered.
Countries are limited to 200 and others (Job titles, Job function, Company Name etc) are limited to 100 for both Include & Exclude combined.
When targeting based on specific criteria with LinkedIn Native filters you should not need to define any exclusion criteria, for example, if you are targeting Canada/USA you would not need to add exclusions for all other Countries/Regions as your include will already take care of that.
