Replace shared activity
I have shared activities and now I want to modify them.
I made the changes on local copies, but I can't see how to upload them to replace the existing activities.
Alternatively, I could edit a shared activity directly, but when I do so in "Open in app" and save the changes, it creates a new activity.
Is there any solution aside from deleting the activity and sharing the modified one? The problem with that is that the URL will change.
