Hi,We have been running a Dynamic search campaign for a about 5-6 years
now. Since mid last year, on some days we've been noticing some weird
spend patterns. Ex: Dynamic campaign doesn't spend during the first half
of the day but spend starts to spike during second half (around 12-2pm
Perth, WA time). We are based in Perth, Western Australia and the search
campaigns run all around Australia. FYI: This hasn't been the case
before and it was always spending pretty close to a "half circle"
