Prodigy, thankfully, after receiving messages from signers like you relating to Level-Up memberships and Teacher referrals, has made it known that they are "working" on it.

However, in the meantime, parents/teachers have to pay at least 2 more dollars to upgrade these memberships manually.

Let's hope Prodigy gets this done soon, and hopefully implements other fixes in the future - with the aid of your signatures.
