Both the "Start + End = Timeline" and the "Sync Subitem Timeline" apps got an update. It is now possible to do the synchronization in both directions at the same time.

Until recently the apps refused to configure both directions (Date to Timeline and Timeline to Dates) on the same board to prevent an infinite loop. When a Timeline change triggers a Date change that in its turn triggers a Timeline change you have the condition for such an infinite loop that depletes your integration count very rapidly.

The new version of the backend code detects these infinite loops and as soon as everything is in sync the app will break the loop. This makes it possible to configure bidirectional synchronization in both the  "Start + End = Timeline" (for items) and the "Sync Subitem Timeline" (for subitems) apps.

Note: when you update a large number of (sub)items at the same time (e.g. by importing items from Excel) it is a good idea to use only one direction. When bidirectional synchronization is enabled (using 2 recipes) a mass update will lead to a high number of integration usage. It is a best practice to switch of one direction when doing mass updates. In the example below the board is prepared to receive an import containing dates. Therefore the recipe to sync a Timeline to Dates has been temporary disabled.
