One tip I would give is to ask questions on their forum instead of their in-app support.
Their in-app support is super reactive but they are sometimes totally ok leaving you with cryptic answers with reference to some underground wiki pages that do not seem to have any relationship with your problem.
Their forum is public so they think twice before leaving puzzle answers.
I am a software engineer, almost always finding my way through any horribly-designed software because I can think like a developper, but boy, this one is complicated for advanced tasks that result in simple results.
