How do I upgrade LinkedIn premium subscription to sales navigator

Hello Adekeye10,

We see you have a question on changing a subscription, and we'd be happy to help out.

This page here has details on changing to a different available subscription type for an app: Change your subscription from Apple

If you have further questions that are more specific to a particular app, we'd recommend reaching out to the company/developers for guidance. We were able to help locate a contact link for LinkedIn here: Contact Us | LinkedIn Sales Solutions

Cheers.
