IF Cititzens → Uma Upgrades
Uma Upgrades is a citizen of Imagine Fun who upgrades legacy Loungefly Backpacks for the player. She can be found at the Storage Shop in Main Street, U.S.A., Disneyland Park.
Upgrading Loungeflies
Some Loungefly bags being sold by other players may be "legacy" Loungeflies, which must be upgraded to the modern Loungefly system in order to be used. Talking to Uma while holding an out-of-date Loungefly will update it so it can be used.
