This type of synchronization works based on "master-slave" model. Text layers can only perform as slaves.

The layers should be in the same synchronization group.

1. Master layer

Open “Layers” item in the settings, click “Sync” section, select “Inside component” in the drop-down list, check “Master” mode and enter the group name.

2. Slave layer

Open "Layers" item, click "Sync" section, select “Inside component” in the drop-down list, type the same group name as for Master layer.

Playback duration of all synchronized layers depends on Master layer playback, thereby, if Master layer duration is 6 seconds, and slave layers duration - 3 seconds, all the linked layers will change the content synchronously in 6 seconds.
