Hi,
I'd like to know if there's a package that works with the Community version and increases the monthly Push limit?
In a word, no.
Sorry. You need a plan, or your own push server.
Thanks for the reply.
How does this Push server thing work? Do you have any how-to material?
Always worth reading the provided docs first.
And
There are a number of people who have written code and instructions on how to do it.
Just do web search for something like “rocketchat setup own push notification server”
In short you will need a push server some accounts, and to compile your own apps.
