Once you publish customizations, the first user to start one of the CRM mobile apps or the interactive service hub can experience performance issues, because their sign in prompts CRM to prepare the metadata package for download. That means the first user should wait for both the metadata package preparation and the download (subsequent users only should wait for the download).
With Dynamics CRM 2016 Update 0.1 or later, you can improve performance for that first user by clicking the Prepare Client Customizations button after publishing your customizations. This prompts CRM to prepare the metadata package right then instead of waiting for the first user to start a mobile app or the interactive service hub.
Hope this helps.
