You may set an static expiry date by setting a string integer.s.cookieLifetime = "86400"; See https://experienceleague.adobe.com/docs/analytics/implementation/vars/config-vars/cookielifetime.html?lang=en. 

@Swanan_ It does not change anything in my comments. I still believe this could be due to Data Insertion APIs being used in server side pages. 

You would need to set up daily feeds and set up the date range for last 12 months. That way you will receive 365 files for last 365 days, 1 day worth of data in each file. Hope that helps. 

I believe moving to SSO is the closest solution you can get. It might not work if people can access intranet/SSO from their personal devices.

If the page does load and fires the event every time on reload, the event will be recorded in Analytics. Recommendation will be to check the code and add fail safe method in the code so that the page does not fall in reload loop. A workaround would be to serialize the event so that Analytics report ...

If the browser id None, that means the data was sent via Data Sources or Data Insertion APIs. Since the page shows "server-side", I guess it is Data Insertion. Can you check internally? You may also check data feed column hit_source and code_ver to validate the source.

This would require a closer look in your data and the query you are running. I would suggest reaching out to Customer Care for further troubleshooting.

Media Analytics (Heartbeat) data is sent to Heartbeat servers (<namespace>.hb.omtrdc.net) first. These hits are then forwarded to Analytics servers (<namespace>.sc.omtrdc.net) internally. BDIA is meant to send data to Analytics servers only. Therefore, I do not think you can send media analytics dat...

I believe dashboard short links are expired after 13 month if they are not used. If you are seeing them expire frequently, reach out to Customer Care to log an issue.

The method is correct. Though, it would be more helpful to look at the code. I would suggest reaching out to Customer Care with debug logs so that the issue can be reviewed in detail.
