My skill has failed certification twice now even though all the testing I do succeeds. We test with the simulator, the app and real Echo and Dot devices. The certification reviewer keeps coming back saying "Alexa, open EnergyCloud" fails and they are correct. We get that error testing in the simulator, but if I remove the comma it works just fine, consistently. I have no control over the comma, or do I?? And besides, the sample phrases that appear on the skill card in the app don't have the comma so I guess the reviewer is attempting to correct my grammar.
My skill connected to a Lambda end-point which I test within the Lambda console. It works.
