It sounds like you’re running into multiple issues now—both with Unigram not displaying the full chat/channel list, and with a keyboard problem (missing a letter). Let's break down your situation and tackle each point:
1. Missing Channel List (Telegram/Unigram)
If the official Telegram app on your phone
also doesn't show the full list of available channels, this suggests it's not specific to Unigram or Windows 11. Telegram does not have a “master list” of public channels you can browse inside the app. You only see channels you join or search for specifically. If you had more channels before, it’s likely those were ones you’d manually joined or searched for.
Key Points:
- Telegram channels only show if you are a member or specifically search/join them.
- Unigram simply syncs what’s in your Telegram account.
- No known public, automatic list of all channels is available in the app.
2. Keyboard Issue (One Letter Not Working)
If a specific letter key stopped working after resizing/resetting Unigram, it’s very likely this issue is unrelated to Unigram and may be:
- A keyboard hardware glitch (try plugging in a USB keyboard to test).
- A temporary software/input bug (a reboot may indeed help).
3. What to Try Next
- Reboot your PC, as you planned. See if the key comes back.
- Log in to the official Telegram Web (Telegram Web) to see if your chat/channel situation is the same there. If it is, it’s an account or Telegram limitation—not a Unigram or Windows 11 issue.
- If you are missing chats/channels you had before, try searching for them by their exact names/handles and rejoin.
4. Not Hopeless!
You’re not alone—this combination of issues definitely feels frustrating, but you're not missing any secret feature!
If, after reboot and checking with Telegram Web:
- The keyboard issue persists, let me know the model of your Lenovo and if external keyboards work.
- The chat/channel situation persists, clarify: Are there specific channels you used to see/access that are suddenly gone? Or are you expecting Telegram to have a browsable list of all public channels (which, unfortunately, doesn’t exist in either Telegram official or Unigram)?
Let me know what happens after reboot, and if you have more details or a sample of the channels you’re missing, I can help you dig even deeper!
