You can unlock the coins from the app.
Yet, the app is currently being refactored and a beta version is available in the play store. Currently the app is not available in iOS.
There are several bugs which we are aware of, for example there are some instances where tickets are purchased within the app and then this does not sync with the desktop.
Another example, twitter is the only social media login option on the app at the moment although the desktop has google, LinkedIn, Microsoft and Facebook login options.
All these bugs are being resolved in the new release.
Rest assured, if you have spent money in the app it will sync with the desktop when the app is finalised.
