Map Night mode incorrectly applied
Since the latest update (v4.1.0) it seems that something went wrong in the map Night Mode: when enabled (Settings → Maps → Advanced Features → Map color mode: Night mode, change automatically) the map turns dark during the day and turns light during the night :-)
I tested this by changing my clock manually: at night (screenshot at 04:33h) the map colours are light. During the day (screenshot at 11:33h) the map colours are dark.
Work-around: disable the "change automatically" and manually enable/disable the night mode
