Why can’t I export a Riverside clip on my phone after editing it on desktop?

If that clip was made in Riverside’s desktop browser, the phone app may only let you view it rather than keep editing it there. Riverside specifically says desktop-created edits and clips are viewable on iOS but can’t be edited in the mobile app, so I’d reopen that project in a desktop browser and export it there. For projects you can open normally in the mobile app, use the recording’s Export button, choose the format and quality, then open the exported clip under Edits and tap Share to download it. If export itself is blocked on desktop, wait until Saving disappears, then check the timeline for missing, archived, unprocessed, or corrupted files.
