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) Create a separate channel/group type (ideal)
2) See the status ONLY for participants who were added by the administrators
The only workaround I found is to send the message as the description/title of a poll setting the vote as public unticking anonimous vote
Probably Skype has good UX in this area: you can see user pic (or several and text +N, when there is too many users read a message) under a message last read by the user(s), you can tap on the list of user pics to see full list, this feature is unavailable for large groups (above 20 users or something).
