I just created/updated the campaign and/or experience and not all devices are triggering?
When you create a Campaign all the data has to reach the devices that are in the targeted segment: this is called propagation. This requires that they have a working internet connection and that they trigger the situations in which our SDK connects to our servers. We recommend the industry standard of 72 hour margin for propagation until your updates hit 90% of the user base. Plan your campaigns ahead and try not to update Campaigns/Experiences on the fly if you don't really need to, it can lower the quality of the Analytics data!
