Hi,
I tried to update the banner to my Developer ArcGIS Online account and although the return was True, the home page is still default.
I am using custom HTML & CSS that I read from a .txt file and that variable I`m passing as a parameter to the method.

The .txt file has custom html elements and css into it, which, if I take it with copy-paste, it`s working just fine.
Has anyone encountered this problem?
Thanks,
Ionut
