When a large number of segments and conditions are used in campaign targeting, it puts an immense strain on the database. To alleviate associated slowness, we may limit the number of segments you can use when applying advanced targeting, or disable advanced targeting altogether. If we do implement any of the following limitations, you will be notified of the change in-app, and alerted if the segments you choose exceed the limiations.
Limiting advanced segments
We may implement a strategy that limits the number of segments you can use that pull from groups and past campaigns. The limit on the number of overall segments will be 5.
Limiting segmentation to groups only
If the load on the database calls for it, we may turn off the ability to segment by past campaign, and limit overall segment to removing and/or adding up to 5 groups.
