Agreed. This issue is not resolved. As jhanten states, the only workaround I’ve found for this issue is to generate an entirely new chart — and don’t forget to make sure every small piece of customization is in place (colors, fonts, pie holes) or you’ll have to start again from scratch. Having a hard time recommending this plugin to my client with this unresolved issue, which is a pity because, otherwise, this is a pretty great plugin!
Oh! By the way, I’ve checked my spam folder, of course. Nothing there.
