I had not paid close attention to the difference between the first notification and the second notification. The first said we would lose Fuel Level, the second said we would lose Battery and Fuel Level.
I've not updated the app, so I am still getting SOC updates. Android app version 5.0.51. There is an update waiting in the app store and it is usually forced after a few weeks.
I have a spreadsheet where I had tracked 99.5% of my charging sessions: start, end times and percentages so after the update maybe only start and end times.
