Smule VIP Subscription Fails to Transfer From Android to iPhone

I have been a user with a VIP membership under the same username on the Smule app for years. While using an Android phone, my monthly VIP subscription continued without any issues. About five days ago, I switched to an iPhone 13 device, and even though I logged in with the same account, the application does not recognize my VIP membership, displaying an "unsubscribed" warning and prompting me to purchase a new, higher-priced membership.

While my VIP subscription remains active on the Android side, I find it unacceptable to be charged again on the same account on iPhone. I demand that my active VIP membership on Android be recognized on my iPhone account under the same username, and that the necessary checks and corrections be made so I can use my current subscription seamlessly despite the device change.
