We work hard to ensure that the Multiple Accounts app supports as many applications as possible, especially ones we know are frequently used and make it difficult to have more than one account, like games and social media apps. However, there may be some apps that Multiple Accounts does not yet support. If there's an app you're interested in using Multiple Accounts for, but you're unable to add it to or open it with the Multiple Accounts app, please contact Support with as much information as possible. We're always looking for opportunities to expand our support for even more apps, and the more requests we get requesting an app, the faster we can try to prioritize adding it to Multiple Accounts! Check out our guide on Unsupported Apps for more info!
