How did it break? Do you have link? Maybe I will be able to help.
In general the plan is to shift away from Elixir’s Logger formatters and backends and instead make use of Erlang’s logger.
So the “simplest” way for “modern” handling would be to (unfortunately) write custom formatter (that implements one function format/2) and then use it together with whatever backend you like.
EDIT:
I will try to provide an example later.
