Cannot purchase anything on OPPO A78: "Error: User Not Authorized"

Hello EA Support and PvZ2 Community, I am writing this post to report a critical issue with the in-game store that is completely preventing me from making any microtransactions. Every time I attempt to buy any item or special offer from the store—including the No Ads Pack and the Crazy Dave Premium Bundle—the transaction is immediately blocked by a system popup stating: "Error: User Not Authorized. You are not authorized to purchase on this device." This is a brand-new account, and this error occurred on my very first purchase attempt. I used to have an older account where I purchased in-game items regularly without ever encountering this issue, but that old account is now gone, and this new account seems to be hard-locked out of the payment system from day one. My device, payment methods, and Google Play Store account are fully functional, and I can make purchases in other mobile games and apps with zero issues, meaning the problem is strictly isolated to Plants vs. Zombies 2. To help the technical team pinpoint why my device or account is flagging this authorization error, here are my exact details directly from the Build Version screen: my Device Model is OPPO A78, Game Version is a:13.1.1 | d:0.0.0, Player ID is DF81A5B8-9C5C-40E1-B566-8A3D4E6F90A1, and EA Device ID is 71bf056ecb1efdb2a6fa38159e59c0da4055784b9bcffcb0eac9fa1954ea5a9c. Before posting, I already tried troubleshooting by restarting the application, clearing the game cache, switching between Wi-Fi and mobile data, and verifying that my Google Play account is properly synchronized, but unfortunately, none of these steps resolved the error. This appears to be a backend restriction or an incorrect server-side flag attached to my new Player ID or EA Device ID. I genuinely want to support the game and purchase these bundles, but the system won't allow me to, so could a community manager or support representative please escalate this to the technical team to review my account status and lift this billing restriction? Thank you for your assistance, and I look forward to your reply.
