I'm not sure I like the usage of different levels depending on the number of occurrences.

I'm not a fan of logging something on the first occurrence and later skipping.
I propose to keep it consistent.

Thank you very much for addressing this!

Could we keep the skip messaging too?

The new warn message is great, but it doesn't let the reader know what the connector's action was (skip) so they can mentally match it to their observed lag/loss situation.
