In the documentation it just says to install the 9.0 cmd-line tools. However UE5.4 expects the "latest" to be installed, as required in SetupAndroid.bat. If 9.0 is required we'd have to edit SetupAndroid.bat, unsure if that is needed though.
Hi @rob42lou,
Thank you for bringing this to our attention. We will go ahead and update the docs to reflect this change.
