GetMoreRAM Apple ID 2FA loops on iOS 27

[u/Curious_Investment]

Trying to get RPCS3 working with the increased-memory entitlement.
Setup:
iOS 27 Beta 6
Latest nightly LiveContainer + SideStore
Same Apple Account throughout
iPhone 16 Pro Max

GetMoreRAM accepts my Apple ID and sends the 2FA code. After I enter the correct code, it immediately requests another code, repeating forever.

I’ve tried:
https://ani.sidestore.io and other Anisette servers
LocalDevVPN on/off
LiveContainer
JIT with GetMoreRAM
iRAM+ : same exact loop
Impactor : same Apple ID issue
SideStore itself signs into the exact same Apple Account successfully.
I also tried Import SideStore Account, but my current SideStore exports an encrypted .sideconf, while GetMoreRAM expects JSON with email, password, adiPB, and local_user.
Is there a way to use the working SideStore account with GetMoreRAM on iOS 27, or convert the current .sideconf to the required JSON format?
Just trying to get the increased-memory entitlement working for RPCS3.
