I have been requested to make changes in an already published survey for staff to record and organize projects, tasks and other info. These changes were mostly adding/removing fields and setting new definitions for choices. The survey has a main feature service layer for general information, and a related table created by the "repeat" type for tasks and deadlines.
When publishing the survey to update, it prompts me a warning that the feature service is not compatible, the related table is not found and republishing the survey will cause the previously collected data to be permanently deleted (see picture below). What did I do wrong? Is there a way to correct this? Any alternatives on how to deal with the situation? The goal for this is to update a published survey with no changes to the previous data. Thank you.
