Timeline Pinning should NOT require Timeline Editing Permissions
Hi,
This new feature is virtually unusable because it is dependent on Access Permissions Timeline Edit Activity enablement. I cannot afford to give hundreds of users access to edit ALL Timelines just so they can pin important activities.
The permissions for pinning should mimic the permissions for cloning. Meaning, the toggle ON/OFF button in Timeline General Settings should control if pinning is allowed globally. Just like how it works for Cloning. These are enabled in the same place so should behave in the same way.

If your intention was to allow flexibility for permission bundles, then make it its own permission.

Forcing people to somehow know they need to go into Permissions for one over the other is not a good user experience.
