If you’ve upgraded to a Vimeo Plus membership in the Vimeo mobile app, you can manage that recurring subscription in the iTunes or App Store (for iOS), or in the Google Play Store (for Android). You will not be able to manage your app subscription on Vimeo.
While you’re an app subscriber, you won’t be able to upgrade to any higher membership tier on Vimeo. If you would like to move to a higher membership tier, you will first need to cancel your app subscription in the appropriate app store, and then return to Vimeo to upgrade your account.
Please note: deleting your Vimeo account will not cancel your Vimeo subscription with Apple or Google. This must be done in the appropriate store.
