it seems like with the forced migration to new workflow tab, bubble didn’t map the IDs of the elements for our dynamic expressions, so we end up with red expressions and issues in issue checker indicating an element is not found, but it is in fact still on the page or in the reusable element. This happens when the element ID is not mapped properly or malformed.
This happens when bugs break the copy paste functions as well. Such an easy mistake to uncover through simple testing.
