Hi Jackiep - I've logged this with Progress tech support, but l also have a Appery.io account. The build to APK is failing in both OEMobile and Appery.io, I use (appery.io) to double check any errors in OEMobile.
Appery.io are generally a few releases ahead of us OEMobile folk.
Katya - I've shared my project in Appery.io, if you need anything else please let me know.
