Hi @DStrine, ran into an unusual and 'serious' bug today where a particular banner does not want to display on Wikipedia.
49 out of 50 times, it doesn't load - I see this code at the top of the particular Wikipedia article I'm on: ⧼Centralnotice-template-B1617_0907_en6C_dsk_p2_sm_rml_mlr⧽
It did load very occasionally, so I thought it might just be a little quirk. I enabled it as part of our weekly Big English campaign - here's the Results Sheet - but took the campaign down after a couple minutes, because I saw no donations or impressions coming in. Its entry did appear in the Global allocation logs.
This banner is an exact clone of an internal banner that loads every time. Here's that other link.
