How do I move on after 807. I do not see any instructions for doing so.

If I play on the Android, I can use mystery quests. However, I cannot do that on the PC. What are the options?

The options appear in the pop up. You can ask friends for help and wait to receive the tickets, or you can use your gold bars to pass. On Facebook, that's the only 2 options.
