When contact detail page is Missing Activity

Our developer, Malde dives deep into this and added more logs to troubleshoot further to find the following reasons: One reason why attribution activity is missing from the contact details might be because the lead fills out the form using iPhone/safari. And this issue happened because the User turns on the option to block all the cookies when form submission happens.

Here is the reference link: https://support.apple.com/en-in/guide/safari/sfri11471/macAnd one other case where we can't track activity, If?notrack=trueparams are present on the URL. ex: https://test.com/?notrack=trueCookies and local storage permissions are required. We are storing user's activity and server session-id on the browser's local storage. If session-id does not store on their local storage or if we can't access it, we can't store contact activity.

For the notes: we are storing every activity but not assign them to contact if the session is not stored or access.
