bot my_chat_member

[alvvaysxxx]

Are there any limits for my_chat_member in large groups (>1000 people)?

The problem I am experiencing is that my bot perfectly works in groups and supergroups, but when it comes to large groups, it does nothing. I can't even track the problem because it doesn't show any bad logs and I can't test it without doing something with production build because I don't have any 1000+ members group so I can manually test it...

"my_chat_member" is a type of an update. What do you mean by "limits" for an update?
