I've looked into this further
When the trail subscription ended ALL my settings for the battery were wiped.
Charging and Discharge settings
Battery discharge limits also wiped
Basically all the settings for my battery are gone.
Even things like battery discharge limits have gone (I think these were set to 10% before)
Is this a bug or normal expectations?
If it's the latter, I really think this needs a clear warning before the trial comes to an end
