I updated the version to 1.3.3 in the store, give that a shot and see if it helps. Otherwise I'll just get my hands on a 6.0+ device to tinker with it. https://play.google.com/store/apps/details?id=com.pm.chalkysticks
Take the recommendations first, but this is the reason I made ChalkySticks (https://www.chalkysticks.com).

The original intent was so you can find bars/pool halls wherever you are; especially if you're traveling. That way when I land in San Francisco and don't know what's around, this will tell me and have pictures.
I updated the Android in the store to version 1.3.3. It should allow you to rotate your device and get horizontal.
