Hello,
I am developing a messaging filtering app (F-Secre) that includes a Message Filter Extension. The extension correctly identifies and filters spam SMS/iMessage.
In iOS 18, when a message was filtered into the Junk folder, the Messages app would correctly display a label beneath it indicating it was filtered by our product, e.g., “Junk filtered by F-Secre”.
After updating to the iOS 26 beta (26.0 (23A5330a)), the filtering functionality itself still works—messages are correctly moved to the Junk folder. However, the branding attribution ("filtered by F-Secre") is now missing. The message appears in the Junk folder with no indication of which extension filtered it.
This is a regression in user experience, as it removes visibility and credit for our app's work and might confuse users about whether the filtering system is active.
