Hi @WumiOjo
Currently Android evaluates boolean values as “true” or "false only (not 1/0). You can follow this guide to check the main differences between Web and Android.
Also, in 2.6 training app we have a “configuration troubleshooting” menu that you can use to see inconsistencies in the program rules created.
Hope this is helpful to you and let us know if you have any other question.
