The data history available for LinkedIn Ads depends on the time range you choose for your periodic dashboard. Industry and Job title dimensions may take up to 12-24 hours to be up to date due to latency applied in LinkedIn Ads' API.
If you choose a daily or a weekly scope, only 6 months of historical data will be retrieved.
If you set a monthly, quarterly, or annual period, the regular 13-month default data history applies. Please note that this limitation only applies to the periodic template.
When creating a widget with one of the two dimensions: 'Industry' or 'Job Title', it is only possible to filter this widget with the same dimension. Attempting to use a filter with another dimension will result in an error message.
