I’m sorry for the late follow up here. Could you please let me know if you have come across this issue lately? @YUL are you still able to reproduce it?
Thank you for your response @YUL!
There has been a fix to address some misbehavior affecting the turn instructions functionality aimed at high level editors, so the reported issue has likely been resolved by that.
I will mark this bug as fixed for now; however, if you come across it again, please let me know.
This appears to be related to Adding Map-Suggestion failed by unknown reasons - the issue has been highlighted to the team and is currently being worked on.
