Hi!
I think the bug that was solved last year is back [1].
I am facing a similar issue wherein I don't see the layer name updating in my storymap's legend. (Please refer to bug1.jpg)
I had renamed the layer as shown in images (bug2,jpg and bug3.jpg)
Can you please help me out in understanding if it is the same bug or am I doing something differently than I'm supposed to in order to update the names in the legend.
Looking forward to hearing from you soon.
Thanks, Ari
