One of our most heavily trafficked web applications stopped working after June update. Popups for the parcels layer, which found intersecting features across a host of other feature layers, just went into infinite loop for most selected features. Culprit seems to be the negative value I had for the Buffer operation. Changing all Arcade expressions to use a centroid intersection instead seems to have fixed the immediate issue, but I'd eventually like to move back to negative buffers, as they provide a more accurate intersecting value.
