Subscriptions and billing

• I'm going to change from Apple to Android, is this going to be an issue for my subscription?
• How do I cancel my subscription?
• Can I resubscribe after cancellation?
• I sign up for the 7-day free trial but I would like to cancel it before it expires. Can I still use the app?
• Can I request a refund?
• How can I change my payment method?
• Can I access my Shido receipts?
• Can I see my payment history?
