What happens to library when subscription is paused

The link: How to switch to a different subscription plan - Apple Support used to specifically refer to Apple Music but now refers to all of Apple's subscription offerings. The things below used to be stated clearly in previous versions of this document:

- " Turn off automatic renewal and your membership will finish at the end of the current subscription period."

- "If you cancel Apple Music, you'll lose access to the Apple Music catalog, any music that you added to your Library, and the features of Apple Music when your current subscription period ends."

- "If you cancel during your trial period, you’ll lose access to the catalog and features of Apple Music immediately."

Now you have to infer this from what is said in the legal documents: Legal - Apple Media Services - Apple

"When your Paid Subscription to any Service ends, you will lose access to any functionality or Content of that Service that requires a Paid Subscription."

You cannot pause an Apple Music subscription. It's either active or cancelled. Once cancelled, any music from the subscription service is deleted, and any music that was matched or uploaded is also removed from the iCloud Music library.

Subscribing again, will match and upload the library from a computer again, like the first time.

No unfortunately.
