Only a few steps are necessary to disable advertising. You can do this by signing up for an ad-free subscription, which is provided by the respective app store. Therefore, make sure that you are logged in to the store with the correct account.
Follow these steps to turn off the ads:
1. Open the Canasta app
2. Tap the gear wheel in the upper right corner (Settings)
3. Select the tab “Game” and scroll down to the bottom of the screen
4. Tap on the button “Ads on” next to “Ads”
5. Choose one of three options - 1, 3 or 12 months - and confirm with “Okay”
6. Confirm your purchase again for the App Store
If the ads do not disappear immediately, restart the app and/or follow the steps above to point 4 and tap "Restore" in the "Ads" menu. This will renew the connection between the store and the app.
If you still see ads, see "Why do I see ads even though I have a subscription?" for more information.
