Difficulty creating variations

Hi everyone, we’re having a lot of problems with Amazon preventing us from creating variations… have any of you experienced this as well (and figured out a way to solve it?) I’m wondering if it’s some recent policy change by Amazon, or if we’re just unlucky to have it affect several of our brands…

Due to the new policy of the Amazon, we are facing a lot of difficulties. You tell us what problem you are facing and I will solve it.
