Ok Long
I couldn't find a link to buy a single plugin. This link you sent (https://metabox.io/plugins/mb-views/), leads to another one with 3 options (CORE BUNDLE $ 99, DEVELOPER BUNDLE $ 199 and LIFETIME BUNDLE $ 499).
So, as I see no other way out, I want to update my license to DEVELOPER BUNDLE. But I already paid $ 99 and when I log in to update, I am being charged $ 199. I understand that only the difference should be charged, that is $ 100.
You can generate a link for this update. Worth $ 100, not $ 199?
Or should I cancel my first purchase and make my second?
