Meter readings.

I’m new to Bulb so still getting used to a new routine. I am a little confused. It appears that every month I’m asked to submit meter readings, under the “threat” of estimated readings if I don’t, and when I submit readings I then get an email that says “another reading in about 3 months would be ideal to keep things shipshape”.

Which is it, what do Bulb want, readings monthly or three monthly?
