Cannot select "do not sell my information" – theSkimm Review

Saw a do not sell my information request from theSkimm app but it doesn't actually work. Submitting generates an error every time I try to apply for the request. Please check that this feature works. I happen to already be a paying subscriber and this is hurting my ability to use the app as I take privacy seriously. Thanks
