Gold Membership Mobile vs Computer

I'm sorry if this question has been asked but so many people disagree or the discussions are too old.

My first question is simple: is there a difference between mobile and computer memberships. Especially concerning gold. Indeed I'm quite taken with the game I find it convenient and the lessons are extraordinary in my opinion. But I can't spend more than 30 bucks on something that might simply be a fad. I don't want to regret spending 80+ for something I know I won't make full use of. But there's the deal:

• on mobile it states that you get to have access to "interactive lessons (beginner)" but if I'm not mistaken beginner lessons are all the lessons you already get for free up to "controlling the center". So what is the point? Is it a typo?
• on the computer however, it is said you have access to 3 lessons per week. It doesn't add any detail to the nature of these lessons (do I have access to the full catalogue?)

also, I've read that before you'd get 3 lessons per day on multiple forums (more than a year old) but in that case this gold membership feels like a sweeping downgrade. So my second question is, is the gold membership even worth it for the 3 lessons per week? On per day would have been alright but three a week seems miserly. But I really do love them. What do you advise o grandmasters?

its not worth, cause you learn more if you just watch good youtube channels like the chessbrahs.
