Non-reproducible. Existing repeat questions can be edited via the 'Sent' box. To enable editing of existing repeats which are opened via the 'Sent' or 'Inbox', the correct bind::esri:parameters must be set to allow querying and updating of the existing records. The following parameter must be set: query allowUpdates=true. See Survey123 documentation for more information on repeat parameters. For 'Drafts' and 'Outbox' of unsent surveys the repeats can be edited as the records have not yet been sent to a feature service and therefore existing records are not being edited, which means the allowUpdates parameter is not required.
