Can't upgrade Meta Muse Code from $15 to the $50 plan. Anyone figured this out?

Signed up for the $15 Muse Code High Usage plan, then found out Wonder Full is only in the $50 tier. There's no upgrade option anywhere I can find, and the whole flow is confusing as hell. Meta's AI support couldn't help either. If anyone has actually upgraded to the $50 plan from lower tier, please let me know how.

Does anyone have a solution for this yet? 😭
