Hello,
It seems that the profile that we can update is only the profile with the core fields and not with the the specific fields of a subscription plans.
Example : first I subscribe to a plan A. Then I subscribe to a plan B with certain fields which are specific to this plan. If I want to update the specific datas of my profile in this plan B, the specific fields are note displayed. I can only modify the commun fields which are the core ones.
That is what I see.
Is it true ?
