Ionic app works on ios simulator but it doesnt work in the real app after deployment, I'm using same server same everything, please help

any ideas how to debug ?

it also works great on web but just not on real device.

Please define what “doesnt work” means. This is not enough information to understand and debug your problem, and so not enough to help you.

Resolved. The URL where i was calling a email service was incorrect.

Best Regards,
Jay
