Aloha! 

Shaka Guide tours purchased directly from the app on android phones are tied to the user's device and Google Account and not to the login that was created to log in to the app.
If you are currently signed in click on Support and then log out of the app. Afterwards, use the Continue with Google option on the login page. You should be able to download your purchased tours once you're logged in with the right Google account. If not, just tap on the menu button and then on Restore in-app Purchases

If this step doesn't work, delete or uninstall the app and download it again from the Play Store. Use the Continue with Google option to log in to the app and make sure you're logging in using the Google account you purchased your Shaka Guide tours with. Use the Restore Purchases option once you're logged in. Again, please make sure you're logging in with the Google Account that was used when the Shaka Guide tours were purchased.  

Should you have other questions or if still is not working, email us at aloha@shakaguide.com or call +1 888 250 2261
