Persistent ''Upscaling Failed'' When downloading images in 2K resolution or more

I’m on the Google Flow Pro plan. When I try to download a generated image at 2K Upscaled resolution (a feature included in my Pro plan), the download fails with an “Upscaling Failed!” error message. This happens consistently across ALL images and generations, not just a one-off attempt. I’ve tried refreshing the page, retrying after a wait, and using an incognito window with cache/cookies cleared, but the issue persists. Since 1K (original size) downloads work fine, this seems to be specific to the upscaling process itself rather than an account or connectivity issue. Please look into why 2K upscaling is failing for Pro accounts and restore this functionality.
