Tiktok introduced attribution manager for their events. From then on, when changing the attribution window to for example 28-day click, the past performance is always reported with the old attribution setting which includes the views. Thus, you cannot compare the past performance with the performance from the moment on that you changed the attribution window.
Request: An unified attribution window for Tiktok (28-day click) or much better - a customisable attribution window (see screenshot).
Additionally, as there is no Complete Payment ROAS metric, implement Complete Payment ROAS (with custom attribution windows) for the Tiktok Ads integration.

Any updates on this?

The attribution window is a fixed ad-group-level setting in Ads Manager, locked once the ad group is published (no retroactive re-attribution via API), meaning this is nothing we can implement on our end as a feature.
