Step 1: Go to ID tool for project Identification Pilot: Onboarding new users
Step 2: open any observation to ID
Step 3: until yesterday, there has been a small binoculars icon behind the user name, when you had clicked on it, it has opened the list with all observations of that user.
This is working as designed. For obscured observations, iNaturalist doesn’t make it easy to find the observers’ other observations and thus removes that link entirely.
