How to redeem solo learn promo code for 14 days free trial

Question

I want to start the 14 days free trial but I need to redeem solo learn promo code

Answer 1

Have you tried contacting [e-mail]? I've never seen any mention of promo-code but that might be because I'm a Mentor.
I thought if you wanted to go Pro, the option was to cancel before the 14 days... maybe it's all changed.
