Re reading the whole thread so that is why I am replying to one that is so far back- Anyway I have seen many reminders about including the "-" and it pops up in AI-Tool also but for me if I include it it will not work, I have to make sure and not use it. Curious if anyone knows why? the way I made the bot originally maybe?Be sure you put a '-' before your Chat ID #, also be sure your bot is invited to the group.
