The S42 provides 5 tee box selections but the Golf app and Connect web only allow 4. Thus, a watch selection of tee 4 translates to green in the app which is the second tee on the list when the round is saved and synced with the app
Edited March 10, 2023:
I am happy to announce our team has implemented the fix to the tee box selection options, which will be available next future update being released. We do not have an exact date for the next update, but should not take much longer to become available. (Capri Isles).
Thanks again for making us aware of the concern, and contributing to the forums!
