I Have Content Hidden Due to My UGC Limit. If I Wait Until Next Month, Will That Content Be Unlocked Using the New Month's Limit?

No, UGC limits are applied on a monthly basis. You can't use your new month's UGC limit to unlock content from a previous month.

However, the good news is that we keep your hidden content stored in our database for a full month. That means you can upgrade your plan in the following month and still regain access to the previous month's content.
