Why has my payment not gone through?
Annually my payment for iCloud is made but this year Apple has problems. Why?
iPad Pro, iPadOS 15
Check -> Go to -> Settings -> your name -> iCloud -> if you see 50 GB (or 200 GB or 2 TB) then you have an iCloud subscription.
If you have an iCloud subscription, you will receive a monthly bill from Apple, check your email box.
If you have upgraded iCloud storage, it would take about 1 to 3 business days in order to process.
Once your request for iCloud+ has been activated, you should receive an invoice in your email box.
If you still need help, get more help and assistant from Apple directly, see Contact Apple for support and service -> Contact Apple for support and service – Apple Support (UK)
