Change zoom subscription from annual to monthly
How can I change my zoom acct. subscription to a monthly account and not an annually paid account?
iPhone XR, iOS 13
From: How to switch to a different subscription plan - Apple Support
On an iPad or iPhone:
1. Open the Settings app.
2. Tap your name, then tap Subscriptions.
3. Tap the name of the subscription that you want to change.
4. Tap See All Plans, then follow the onscreen instructions to complete your purchase.
For other devices, read the support article.
I believe that applies to all subscriptions, not just Apple ones such as Apple Music.
