Answer
Use Keep Editing to retain your description and screenshots when closing with X or Back. If submission fails after the form closes, Open Report returns to the draft so you can retry.
Draft recovery includes the description and successfully uploaded screenshots for up to 24 hours. Uploads interrupted by restarting may need to be selected again. Their slots stay visible and removable so they cannot silently prevent submission. Wait for uploads, retry failed screenshots or remove them before sending.
Uploading and submitting do not wait for automated investigation. A damaged or unavailable attachment does not discard a description that was already accepted. Older installed apps and recovered drafts can still use the earlier reporting path. Message and hashtag reports also close while sending, but moderation-email confirmation can wait for the email provider.
