No. The partner cookie attribution in the GetYourGuide app is currently not supported.
However if the link or widget (that the reader/customer clicks) contains a valid partner hash/partner cookie ID, we redirect visitors to the mobile version of the GetYourGuide website and the regular cookie attribution applies. This means that in this case the app is blocked from being opened, if it is installed on the user's device.
However we consider to enable cookie tracking in the app in the future as well.
