I woke up to the time change this morning (Germany changed to wintertime this morning) and everything is fine on my AnkiDroid app.
However, on my Linux Desktop - all cards have a due date one day earlier.
I have resynced, I have studied on my Android and synced, I have forced an upload from AnkiDroid and resynced, and nothing changes this.
I set the “next day starts” to a later hour on the desktop, and then things line up (apparently because the desktop no longer expects me to study tomorrow’s cards today) … but then, when I sync again, this needs to be changed back on Android.
I have the latest AnkiDroid. I have the latest Linux desktop version of Anki. The desktop version is showing the wrong dates. It’s the same synced set of decks, but the due dates on the two devices show up differently.
