I'm having difficulty using In-App Messaging and I do not know how to solve this problem.
I created a campaign and sent a test to a device, and this test never succeeds. Today I was surprised by the message being displayed from a test I had done three days ago.
I've read and reread all of the In-App Messaging documentation and all the steps were followed correctly, but I've never been able to make it work.
After all, does In-App Messaging work on iOS or is it just a proposal to maybe work in the future (if it works)? Honestly it's pretty frustrating something so simple does not work.
