Getting rate limited by facebook server

[pictuga]

When doing the initial backfill, the bridge seems to be rate limited by facebook

This results in empty conversations

Is there some way to handle this?

@tulir facing the same, how does beeper solve this? Not backfilling thousands of old messages but limiting to a few hundreds? Or limiting bandwidth to prevent it from being too fast?

What's the reason why the backfill skips rooms that have no messages in matrix?
