Currently, cross-platform purchases are not available on Vimeo. For example, if you purchased a membership on the Vimeo website using a desktop browser, and then switched to the Vimeo mobile app to make your videos and wish to upgrade your account, you would need to go back to the website to purchase the upgrade.
If you attempt to upgrade your account on a different platform, you'll see an error message saying “You started this purchase on another device. Please continue on that device," instead.
A device, in this context, refers to the website (regardless of supported operating system or browser) or the Vimeo Android app, or the Vimeo iOS app.
