Exporting to midi on Hookpad 2 Beta

Despite being a member of Hookpad+ when I attempt to use any of the export functions in Hookpad 2, I am granted the following pop-up:

I’m not sure as to what is causing this issue; however, it has been preventing me from exporting my song for the past few days, and I’ve made sure I am logged in. If I were to guess what the issue is, I would say that it could be due to Hook[ad 2 not being synced to the list of users that have Hookpad+. If anyone has a workaround I can use until this is fixed, please let me know; otherwise, I hope to see this fixed as soon as possible.
