FYI: Google is removing the ability to have independently configured conversion windows in GA4 and Google Ads.
After March 31, GA4 imported conversions in Google Ads will solely use the GA4 settings.
GA4 allows you to select 30, 60, or 90-day conversion windows.
Google Ads did offer more flexibility in letting you pick any length you wanted, from 1 to 90 days.
If you’ve used this feature, it’s time to rethink some.

NB: Although this message is about imported conversions, I always recommend to use Google Ads conversion tracking instead of importing conversions through Analytics.
