Friends, here comes a long-awaited feature! Now you can filter out duplicating messages.
For example, if you are subscribed to two channels and the author of the second channel constantly reposts from the first channel, then you will receive these messages only one time.
The function is available only on paid accounts.
You can enable it for all sources with the command
/setting duplicate filter
For a specific source use the command
/settingchannel @source duplicate filter
