The charts I’ve built that use a Template as the split type have stopped working. Where the series split values would typically show up in the legend, there is just a “Loading…” message and the split isn’t happening. If I switch the split type back to “field” it works fine, but then we get the not-so-atheistically-pleasing (SUM) after all of the values.
I have so many charts on so many pages, and I always split by template because it looks better in the legend. Would love to figure out how to fix this without having to change all of the charts.
