imo it is reasonable to call after it shows online to see if anything is missing, if nothing is missing they will probably give an answer of 'it is in process call us back in a month if you haven't heard anything' but if this is your first attempt at a license you can call once it shows online to ensure you crossed all the t's and dotted all the I's but then you may as well wait until 1 month after because the mandatory wait period. When I first applied years ago I was approved as soon as my wait period ran out.
