Minor annoyance but not a big deal.... I have an iPhone with Night Mode enabled in the OS but I prefer to use this site in regular mode and not Night Mode because visually the Night Mode is a little tough to read. For the site I have disabled auto-detect and night mode both, and on two occasions they have reverted back to enabled (both after roughly a couple of weeks). I didn't have to login again or anything to cause it, it just enables automatically. It just happened this morning.
