Laravel Cashier & Stripe Subscription Renewals

I have implemented a subscription package on my application using Laravel Cashier and Stripe.

I would greatly appreciate assistance with understanding the following things please?

• Does Stripe automatically renew a subscription and generate / send an invoice at the start of a new billing cycle? Or would I have to setup a cron job to renew subscriptions and send invoices?
• What is the recommended approach to sending the user an email when issues with renewing a subscription arise such as declined cards?

I have spent a long time looking for the answer and have been unable to find anything.

Thank you in advance for any help.
