so do mine after the update, tried reset the map and it even worst, not even cover 10% of the area and declare job complete. with maps, at least it try to travel all around.
currently, tried to hard reset to factory setting and trying now

1) Tried on / off. Not working
2) Tried reset map. Not working
3) Tried hard reset. Not working
4) Shut off for a night, turn on next morning. Somehow it acts normal and able to complete the full course.
5) Keep it powered, the next day try again.. start acting up. on/off still the same. After charged, turn off for the day.
6) Next day, power up and try again. back to normal and finish up properly.

so right now, can't set automation for it. Need to shut it off after the battery charged and turn it on when want to use it.
