Audience & segmentation
Tags, segments, filters and geozones — deciding who receives a message.
Segmentation & targeting
- How do I update tags for one device from a backend server?
- How to format list tags in a CSV file for import
- Can I change a tag type after I create it?
- What is the difference between application-specific, application-nonspecific, and user-specific tags?
- How do tags, segments, and events work across multiple apps in a single account?
- How do I send push notifications to a list of users via CSV file upload?
Troubleshooting: audience & tags
- Why does my CSV upload for audience creation show rows skipped?
- Why is the 'City' tag missing for some devices even though the 'Country' tag is set?
- Why is the number of users in my Segment lower than the number shown in Tag Statistics?
- Why is my calculated segment size much smaller than the estimated size shown in the preview?
- Why is my test device showing an 'Unknown Platform' and the QR code registration is failing?
- Why do some users appear in two segments that should be mutually exclusive (e.g., users who performed an action vs. users who never performed it)?
