Dear Support Team, I am writing to seek technical assistance regarding a persistent issue with Dolby Vision exporting in DaVinci Resolve 20 on my iPad Pro 12.9-inch (2021, M1 chip) running iPadOS 26.0.1. The Issue: Despite correctly configuring the project for a Dolby Vision workflow and successfully completing the dynamic metadata analysis, the "Dolby Vision Profile" dropdown menu (and related embedding options) is completely missing from the Advanced Settings in the Deliver page. My Current Configuration & Steps Taken: Software Version: DaVinci Resolve Studio 20 (Studio features like Dolby Vision analysis are active and functional). Project Settings: Color Science: DaVinci YRGB Color Managed. Dolby Vision: Enabled (Version 4.0) with Mastering Display set to 1000 nits. Output Color Space: Rec.2100 ST2084. Color Page: Dynamic metadata analysis has been performed, and "Trim" controls are functional. Export Settings: Format: QuickTime / MP4. Codec: H.265 (HEVC). Encoding Profile: Main 10. The Problem: Under "Advanced Settings," there is no option to select a Dolby Vision Profile (e.g., Profile 8.4) or to "Embed Dolby Vision Metadata." Potential Variables: System Version: I am currently running iPadOS 26. Apple ID: My iPad is currently not logged into an Apple ID. I suspect this might be preventing the app from accessing certain system-level AVFoundation frameworks or Dolby DRM/licensing certificates required for metadata embedding. Could you please clarify if the "Dolby Vision Profile" option is dependent on a signed-in Apple ID for hardware-level encoding authorization, or if this is a known compatibility issue with the current iPadOS 26 build? I look forward to your guidance on how to resolve this. Best regards, INSOFT_Fred
