Auto-night mode doesn't switch back to light theme
Auto-night mode does not work as intended when set to either system default, or adaptive, or schduled by time, or scheduled by sunrise/sunset time. In both cases Telegram switch to dark mode, following…
1. Accepting ~1k users.
2. No reaction for a long time because there is no notification.
3. Repeat steps 1 and 2 multiple times.
4. At some point someone notices it (for example, some channel that posts news about TG).
5. More users starting to check it.
6. As a result, more flood and spam, scaled with step repeats.
It's better to notify ~1k people than to deal with ~10k or even more. Plus, not everyone will even create a card, so that's already less than ~1k.
I have alternative suggestion though. In window that blocks card creation, add a button "Notify availablity", so only those who really want to create a card, will be notified. And of course, since buttons are not on plain sight (you need to open a card or search first), only those who want to create cards, will be notified.
Speaking of the steps you provided, yeah it makes sense. However, still I can't figure out why they're rolling out gradually if they're not afraid of spam.
