If you have any problems with the Facebook game Tetris Battle, then you should see if third-party cookies are enabled in your browser. Often they are not. Therefore, the error message „We are having difficulties logging into Facebook. Please try again later.“ appears in many browsers.
To fix this problem, you can do the following:
- For Mozilla Firefox: Enabling third-party cookies until they expire
- For Google Chrome: Allow cookies by default
Thanks to the Tetris Battle Online Customer Support for this information!
