Links from the Place Detail page to Foursquare:
Problem: You have the Foursquare native app installed on your phone. You are on a Place Book place detail screen and you click on the Foursquare button. Android asks you to select the Foursquare native app or browser and you select "browser". Then Foursquare closes without even starting and you go back to the place detail page.
Solution: Go to the Android menu, click "Preferences -> Link to Foursquare" then select "Native app". Then you should be able to press the Foursquare button, select native app when Android prompts you, and you will land on the Foursquare place within their native app.
Known issues we are working on:
We are working on supporting the newer version of embedded Google Maps which has changed from "tiles" to vector format. All this means is that you won't see the tiles flashing in and out of view.
