Problem receiving channel messages by 5k+ members

[robertoenr]

Hi,
I want to receive all mesages from public channels where I’m subscribed on real time. So I’m overriding the onTLChannelNewMessageCustom method.
But I’ve noticed that this method doesn’ get called by Api when a message arrive to a channel or group with more than 1500 members.
It’s only notifying with channels or groups with ~150, ~300, ~700, ~1017 members. With groups with 10000, 20000, 30000, 40000 members does not work.

It’s an api problem with notifications?

Any solution for this?
Thanks.
