weebzone/Telegram-Stremio v2.0.1 on GitHub

What's new

Instant sign-in: accounts with many chats no longer sit on the start-up screen; chats load in the background.
One library per Telegram account: signing in with another account starts empty (with a restore offer); logging out backs up the current library first.
Imports keep scan progress: after importing a TeleStremio or Telegram-Stremio backup, channels continue from the newest imported file, so only new posts are scanned.
Channels from imports: Telegram-Stremio backups without a channel list now add every channel that has files, with its name.

Importing a backup no longer leaves scan progress of the replaced library behind.
A scan that gets no messages from Telegram is no longer marked as done.
Clear library also removes custom catalogs.

Android: arm64-v8a for most phones, universal if unsure.
Windows: .msi · macOS (Apple Silicon): .dmg · Ubuntu / Debian: .deb
Server / any OS: java -jar telestremio-<os>.jar --headless with the TDLib library next to it.
