I've had to report on users for previous media companies I have run. Using a daily number will make the overall number seem higher than the monthly total unique users.

Here is an example of one site I ran a long time ago to illustrate:

Average daily unique users: 111,000 Total unique monthly users for the same period: 2MM unique users.

I could see how the interpretation of the average daily might have someone inferring it's x 30 for a month so call it 3.3MM users during the month but the actual monthly total is lower.

I don't think there is anything wrong with reporting daily especially if it's the type of site or app where the user is likely to be there on a daily basis vs say the websites of the past two decades where half the readers only come once and the other half come 2 -10+ times.
