Snapseed making my photos duller/dimmer after saving

iPhone 16p.

I've been using Snapseed for years and never really had an issue before. But recently, I noticed when saving my photos after editing (either "save a copy" or "export"), the saved photo is much dimmer and duller. Like it loses vibrancy when comparing with the original.

This happens no matter which edits I do, whether it's a small color correction, adding warmth, etc. Basically, anything I do in the app, if I save a copy of the photo, it ends up losing vibrancy. Now, if I simply save a copy in Snapseed without doing any edits, the photos looks identical to the original.

This was never a problem before for me. I'm sure I would have noticed. I am editing HEIC photos. And I have settings set to "not resize."
