Sometimes we forgot to add an important detail, or maybe in retrospect you had more impact than you realised. When that happens, you can update an existing log.
To update a log, find it in your log by selecting the log date in the sidebar, or in the = menu on mobile.
Once you've found the log you want, click Edit, which is beside the date of the log.
From here, you're in the usual log page, and you can update any details you'd like!
