Description Nicolas 2025-10-02 20:29:44 UTC

SUMMARY
After upgrading from plasma 6.4.5 to 6.5.91 the day-night time settings were reset to "automatically detect location" using geoIp (which was wrong). I did set it up manually before however, resulting in night time mode at day. 

STEPS TO REPRODUCE
1. In 6.4.5 set manual location for day-night-cycle
2. Upgrade to 6.4.91 (6.5 beta 2)

OBSERVED RESULT
Night time settings are not kept

EXPECTED RESULT
Settings should be preserved during upgrades

ADDITIONAL INFORMATION

Comment 1 Nate Graham 2025-10-03 16:04:39 UTC

The settings moved from the "Night Light" KCM to a new "Day-Night Cycle" KCM. It's quite possible that old settings weren't migrated over to the new thing.
