@Bruno-Garcia I managed to delete my routes based on this guideline.
@Mff73 said in How to erase Clock routes?:
If we are talking about routes (in watch navigation menu ), in Android you can “delete” them like this
1- Go to Android settings --> Applications --> SuuntoApp --> Delete storage
2- It will delete locally all your SuuntoApp datas, but, normally all is synced in cloud
3- Reconnect to you account, repair watch and sync
4- Normally your MC routes are now synced in SA and you can toggle them off and then delete them.
I has worked twice for me.
